    The weekly 50% water change.... why?

    It's suggested that you review the EI Dosing article in the Tutorial section of the forum. This is what happens when folks make assumptions about a technique that they don't fully understand. In Post #18 Tim Harrison refers to a thread with an identical question. The guy who invented EI responds...

    Need some tips for moving plant

    Hello DuyHung, If your older emersed leaves are failing then it means you have some combination of too much light, poor flow, and poor CO2. It's the same story if someone gives you a plant from their tank and you get problems when they are placed in your tank. Moving the...

    when to start using ferts

    There is a huge difference between a CO2 vs a non-CO2 tank. It is the same relative difference between a Formula 1 car vs a farm tractor. Although Paulo is correct that plants need light, plants in a non-CO2 tank do not need nearly as much light as most folks seem to think. There is a lot of...

    Just a quick question about converting to low tech

    Hi, You can simply leave the lights off and restrict dosing nutrients, assuming the tank is not in a sunny area. The plants will lose weight and the dim available light will help to reduce the chances of algal blooms. When you do restart the light, obviously make sure it's a lot less than...

    Too much or not enough light?

    Hello, BBA is a CO2 deficiency related algae. There are many BBA threads available, and in general, correct attention to CO2 techniques, as well as to flow/distribution is necessary. Cheers,

    Tank Restart Questions

    Hello, BBA spores are likely to be in every tank in the world, so there is no point worrying about that. BBA blooms occur because of what we do or do not do in the tank as explained in the post=> cleaning dry algae from a used tank So you'll need to get a full understanding of the...

    Dark Start, Ammonia and Ammonium

    Well, nothing drastic will happen. That will still be below the crossover point as shown on the chart, so most or all will be NH4. That is correct. The soft clay pellets are soaked in a nutrient solution. In order to mineralize the NH3/NH4 to NO3 the oven needs to be around 400 degrees.F. for...

    Dark Start, Ammonia and Ammonium

    Hello, It's not as simple as just lowering the pH. In toxicology a general rule is that the concentration determines toxicity. The majority of folks using Aquasoil are also using CO2, which does lower the pH and they may still suffer toxicity as there is a LOT of NH4. In any case...

    "Aquarium Science" has some new planted tank articles

    Exactly. He's aware of EI but has he tried it? Don't know. His claim is easy to falsify, right? EI dosers add too much ferts and don't get algae. We can add the appropriate nutrient to a tank experiencing algae and the bloom is reduced or eliminated, further falsifying the claim. Cheers,

    "Aquarium Science" has some new planted tank articles

    Yeah, this is just more pseudoscience from The Matrix. I love the part about phosphorous's limited solubility. I wonder if the municipal water companies who dissolve PO4 in the systems are aware of this so-called fact. I never knew it was impossible to keep lots of fish in a planted aquarium...

    How often to deep clean a planted tank?

    Hello, BBA is a CO2 related algae. It is not directly related to sediment waste buildup. Dirty sediments in a CO2 enriched tank however can contribute to some types of algal blooms since there is a high ammonia content in the sediment. If the sediment is disturbed at a time other than...

    First algae alert ⚠️: Brown algae killing carpeting plants. Help!

    These are classic symptoms of poor CO2. The DC should be green when the lights are first turned on. It would help to reduce the light intensity. Also, lowering nitrate in a planted tank is a really bad idea, although doing a lot of water changes is actually a GOOD idea, because that keeps the...

    Reduce water change frequency with EI ?

    It's as Marcel mentions. There is no formula to determine how much light, what kind of flow/distribution and so forth will be required. You just have to experiment and see what you can get away with. You might get lucky, or not. Cheers,

    What would trigger algae to grow on glass?

    Hello, Algae in planted tanks is always caused by too much light and either not enough nutrition or not enough CO2. The typical algae on glass is Green Spot Algae (GSA) which appears, as the name implies as groups green spots. Algae forms on hardscape because it is easier for them to...

    New tank care and maintenance regime feedback needed

    OK, there is a video on that link with George waxing poetic about it, so I would have to assume he would only do so if it is an all-in-one. But still, why pay for water? Good call mate! More sense always works! :cool: Cheers,

    New tank care and maintenance regime feedback needed

    Hello, A daily water change is not really necessary. A 2X-3X per week is all you need. No idea what "EA complete liquid plant food" is but you should ensure this product actually has, in fact NPK plus micronutrients. Always be wary of commercial fertilizers claiming to be "complete"...

    Water change 50% net or gross ?

    Yep, it is a sight to behold when you get the salt tank set properly, but it's in the "just too hard" category. Hope your friend finds the info useful The sumps really do add a lot of water. I add up the volume of my four modules and they total about 100 US gallons versus the tank which is about...

    Water change 50% net or gross ?

    Yes, ferrous gluconate is a popular addition used as a component in some commercial mixes as well as in DIY mixes, but you're only adding small amounts to raise the iron by fractional amounts, like 0.4ppm. But no, as mentioned, plants cannot use this carbohydrate. The Rubisco molecule only...

    Wow, do people still use buckets in 21st century? Why not just get a 50 ft. hose and a cheap submersible pump to get the siphon started? Use a spring clamp to affix the hose to the glass (or a Shepard's crook to hang it over the glass). Then use the pump on the other end if the fill water is...

    Water change 50% net or gross ?

    Hello, Do whatever method is easiest. Everything are approximations and there is no penalty using whatever method you choose. That's why the word "Estimative" is used. For changing water you can simply use the height of the tank. Again, this is about 50% but you are not constrained to...

    Maintenance during photo period

    Hi Michael, Well, you maybe can get an idea of the amount of CO2 dissolved in the same way as the pH profile by looking at the difference in the CO2 values on the pH/KH/CO2 chart. Again, we would have to make the assumption that the rise in pH is due 100% to the dissipation...

    Purple Non-Sulfur Bacteria?

    I suppose there are those that will argue but the general consensus on this board at least is that BBA and red algae in general are CO2 related algae. DOC plays a role in just about all algal forms in a planted tank due to it's effects of lowering dissolved oxygen due to bacterial action as well...

    Purple Non-Sulfur Bacteria?

    Hello, I'm always leery of products being pushed for sale without any actual data to show it's benefits. It happens that the bacteria and archaea that we are already familiar with, such as Nitrosomonas, Nitrobacter and so forth are themselves Chemoheterotrophs and Chemoautotrophs...

    Maintenance during photo period

    Hi Michael, Often, CO2 dissolves into the water supply simply due to the path that the water takes through aquafers on it's way to the municipality. Since it readily reacts with water to form the weak carbonic acid it is added by some water companies to reduce the pH (or the...

    Maintenance during photo period

    Hi Michael, Yes, CO2 molecule is too large to fit through the membrane, so if using RO water for the water change there will not be any CO2 present, so this can be taken out of the equation. Also note that not all municipal water supplies have CO2. As I'm sure you're aware it's...

    Maintenance during photo period

    Hello, The advice is a general rule that may or may not apply. For CO2 injected tanks it's better to do the water change before the light go on or just prior to the gas being turned on simply because most municipal water supplies have the water enriched with CO2. This CO2 is an added...

    PH profile, good then bad?

    It doesn't even matter if you have 15 DCs.

So there is no point in using multiple DCs. Simply...

    Britta filtered water good for plants?

    Hello, Tap water is fine for your plants and in fact may be better for the plants than filtered water, however, use whatever water you deem appropriate. I don't see any reason tap water should be a problem for your sediment. There is no excuse for not knowing what's in your water. Your...

    Algae or not enough C02?

    Hello Aaron, While it's not an emergency I suggest simply turning down the lights until you powders arrive. Micronutrients are not really that important. I don't know why everyone gives them so much credit. The important nutrients are the macronutrients Nitrogen, Phosphorous...

    Algae or not enough C02?

    Hello, This is one of the cardinal sins of plant husbandry. Plants do not care about acidity unless the acidity is being caused by some toxic acid agent, like pool acid. It's the same for the fish. Even more appalling is the fact that those fish originate from tributaries and streams...

    Is there any difference between the color of the lights for planted tank?

    Yes, but again we are not growing plants outside the hobby. We are growing plants within the context of our hobby and in so doing it turns out that there are so many more factors that affect the growth and health of aquatic plants that the effects of spectral distribution are rendered...

    Is there any difference between the color of the lights for planted tank?

    Hello, There is no difference between any color light that you may choose to use. As mentioned, the subject has been thoroughly discussed and no one has any evidence in our tanks that spectrum has any value other than an aesthetic one. Plants simply adapt to the lighting provided and...

    Fluval Sea Liquid Calcium

    Hi Steve, I agree with three-fingers mate. As far as plants go, calcium is a micronutrient, so it's content merely needs to non-zero. If your water is soft, or if using RO, you can always used the crushed-coral-in-the filter routine. If using hard water from tap then yeah, it's...

    Advice about planting in multiple sessions

    Why bother? Whatever plants you have, plant them, fill the tank and carry on. When new plants arrive either plant them directly, or if you find it easier, drop the water level and plant. This should never be an issue. No one ever has all the plants they will obtain at one time. Cheers,

    Diffuser under intake

    Vaccum the soil to avoid algae ?

    Well, yes there is a war between algae and plants, but it is not a war of who can eat the most nutrients because algae do not care about the nutrient level. Algae are predatory and they can get all the nutrition they need by simply attacking and collecting the nutrients from dying and unhealthy...

    Vaccum the soil to avoid algae ?

    Hello, These statements are completely incorrect. Plants and algae do not and cannot possibly compete. As mentioned by other posters, doing water changes and keeping the tank clean is always a good thing. Organic waste produced by plants and animals accumulate and reduces oxygen...

    New tank trouble

    Hi Andy, Perhaps I phrased it inadequately. I did not mean that CO2 is bad for plants. There is no such thing as too much CO2. What I said was that NOT ENOUGH CO2 is bad for plants. Using a yeast based system is a very bad way to apply CO2 because it does not produce a sufficient amount of...

    New tank trouble

    Hi Ady, Yes, I highlight poor oxygen because it exacerbates the problems caused by poor CO2. CO2 is critical as it's consumption produces food in the form of carbohydrates (sugar). Having produced sugar the plant then can only produce energy by using Oxygen to burn the...

    New tank trouble

    Hi Nick, Well, you're right. it's a combination of poor CO2 during the day and poor oxygen at night. Doing a dry start doesn't really save you when the plants are flooded. This is a gas exchange issue and so it doesn't take long to suffocate, or to drown. Who knows how much...

    Aeration and Oxygenation with co2

    Hi, Yes, sorry, as pointed out by wookii this is completely wrong. Oxygen, CO2, Nitrogen and other gases coexist in the water and none can affect the concentration of the other. Despite what many think, air bubbles do not actually add any oxygen by the mere fact that they are air bubbles...

    Plant deficiencies? and leggy growth

    Hi Nick, Well, I mean, you could ask that question of just about any plant and the answer is always that if the newly submerged plants do not get enough gas due to errors in CO2/Oxygen/flow/distribution, then yes, the leaves can die off rather quickly. If you previously had not had...

    Hi Karl, The elongation is triggered by a combination of O2 and CO2 shortfall. As you mention, other things are happening during the blackout as carbohydrates are consumed and are not replaced, so there are some structural issues going on as well as a fall in Oxygen production. The...

    Why can't I grow healthy plants? What am I missing? - Now improving!

    Yeah, for sure mate. What I do is to buy a length of cheap PVC tubing and then to try different lengths with different hole sizes. I try to get away with as short a length as I can with as large a hole size as I can. Sometime I use variable hole sizes along the bar. So for example you can try...

    Why can't I grow healthy plants? What am I missing? - Now improving!

    The primary purpose of the ceramic rings is actually to slow the flow so that the larger particles of debris fall out of solution and to be trapped within the maze of rings. They do house bacteria, like any whetted surface but that is not their main function. That's why it's so critical to avoid...

    OK, well, I mean generally, when you have that symptom of bubbles collecting on the surface, it means that the flow rate is poor and the bubbles are not making it to the bottom of the tank. The result is that the CO2 concentration is high near the water's surface, but is low in the plant beds...

    This is a flow distribution problem and has nothing to do with light. Leggy growth is a symptom of poor flow/distribution. As Ian points out, there is a severe lack of energy coming from the spraybar. Additionally, it's position is too far to the right and the powerhead is too far to the left...

    Plants with out a filter

    Hello, If I were you I would simply fill a shallow bucket of water and float the plants in the bucket until you are ready to plant them properly. Keep the bucket out of strong light and just carry on. Cheers,

    Holes in AR leaves

    Any auxiliary pumps should be placed at the center just below or above the spraybar in order to augment the flow/distribution patterns from the spraybar. Tall tanks are always problematic because the energy required to evenly carry the water down to the bottom is high. If you place the pump at...

    Holes in AR leaves

    Hi, Check first to see if the the cause is predation by snails or other vermin. Holes in leaves or any structural fault which is not due to predation is caused by a CO2 deficiency. Cheers,

    lighting suggestions

    General rule of thumb is that the worst thing you can do when starting a planted tank is to focus on how much light you have. Plants growing fast have nothing to do with plants being healthy and it is much more likely that if you have so much light that plants grow fast then algae will also grow...

    H2O2 dip recipe

    No, all types of spores eventually find their way into the tank and bloom as the opportunity presents itself. As I mentioned, if the plants are healthy the spores just sit and wait. Yes, you are right, there is much fuss made. It's much more important to have the tank healthy than to dip...
