    Algae due to nutrient imbalance caused by 1 plant?

    Hello, Hair algae and BBA are classic symptoms of poor CO2. My advice is to concentrate on fixing this by reducing the lighting and ensuring that you have good injection rate, good timing of CO2 application and good flow/distribution. The issue regarding "proof of nutrient depletion by...

    Water Flow Sensor ?

    Yes, you're right mate. I missed the bit about the alarm. It might be better to monitor the pump circuit as you mentioned. Lots of sturdy and reliable equipment available for that. Cheers,

    How important is hardness vs. other conditions?

    Hello, Yes, hardness is never really a problem for all but a handful of plants. Lighting and CO2 are the main culprits. Here was a tank with a GH of about 23 GH and 26 KH. Cheers,

    Water Flow Sensor ?

    Yes, get a bucket of known volume and see how long it takes to fill it from your filter outlet. Then do the arithmetic to determine flow rate. Cheers,

    Low ph in a 2yr old set up

    Hello, I agree with alto in post #7. Trying to adjust pH for the sake of pH will only cause more problems than it would solve. The fact that the condition has existed for 2 years and that you fish are breeding in this water is absolute proof that this is a non-issue. The fish that you listed...

    Can High Temps Cause Algae?

    Hello, yes, definitely, all other things being equal, tanks with higher temperatures are more prone to algal blooms. Algae can survive in temperatures high enough to kill most plants. As noted by other, high temperature alone is usually not a sole factor in algal blooms. Excessive lighting...

    Hair algae

    Hello, Too many nutrients do not cause algae. On the other hand, not enough nutrients causes algae. Hair algae is always caused by not enough CO2, so you need to address either the amount being injected, the timing of the injection and, as noted by paraguay, you'll need to ensure...

    Why exactly do we dose EI on alternate days? . . .

    The answer to this question is exactly as stated by sparkyweasel in post #5. Yes, it is true that Fe and PO4 reactions "can" occur in some tanks, especially if the water is hard (one will observe the precipitation of Iron Phosphate), however, you "can" get away with dosing both on the same day...

    Converting Reef Metal Halide, which bulb Kelvin?

    I agree with foxfish. There will not be any measurable difference in plant growth/health due to color temperature. What's more important is to use a color or a mix of colors that you find attractive. Cheers,

    How to combat BBA?

    Hello, Yes, you are correct. Poor CO2 is the root cause of BBA. Is this a non CO2 injected tank? I'm assuming so. If that's the case then the only options are to reduce the CO2 demand by reducing lighting. When you do the water change you can spot dose either hydrogen peroxide or...

    Spray Bar and Tall Background Plants

    Hi, I see no reason why you can't implement the scheme even with background plants. There will be some disturbance but so what? Ideally, CO2 should be distributed in both, but this adds a lot of complication. I would try just with one and see how it goes. You can also add a Koralia or...

    Curled and blackened leaves

    Hi, No, sorry it does not. Excessive phosphates do not cause algae, and therefore it is something that you never need to worry about. The worst thing you can do to analyze your problem is to spend you hard earned money on a PO4 test kit. This will only lead you down the primrose path that...

    Why do commercial GH boosters have such high K?

    Hello, The addition of K2SO4 is unnecessary to raise General Hardness, as I'm sure you're aware. Tom Barr adds it simply to help those who, for example do not use EI fertilizers, the main components of which are KNO3 and KH2PO4. If these main components are not used, in the dosing...

    Holes in leaves

    Hi, As Zeus mentions, It's very difficult to compare two different tanks. Often, we assume we have control of the environment but more often than not, this is an illusion. Just a degree or two difference in the water can result in differences in CO2 content. Differences in the amount of...

    Holes in leaves

    Yes - for some plants such as stems and carpet plants. Shrimp react poorly to this substance though, so best to be careful. This is an expensive fix if your tank is a CO2 injected tank. It's a better solution to reduce the CO2 demand by reducing the light intensity as mentioned above, and by...

    Plant doctors to the emergency! Please help

    Hello, It really is a very bad idea to add acid to your tank. Phosphoric acid is a highly toxic material and will have long term ill effects on your fish. Fish do not really care about pH, but they DO care about WHY the pH is what it is. In this case they will ultimately care about the...

    GSA on all the plants... Help!!!!

    Hello, GSA is caused by any combination of poor CO2 and poor PO4. You have listed in your configuration the item 4. ADA Amazonia, which, if this is new substrate (i.e. less than a year old) then there is plenty of PO4. Therefore, we should assume that the condition is cause by poor...

    Types of FE, chelated? edta? dpta?

    Hello, This is one of those situations where we make life more complicated for ourselves with very little to show for it. Iron is a micronutrient, which means the plant only needs microscopic amounts of iron. About one hour after you have dosed iron, the plant has already taken up it's...

    Hi, Grass cuttings will also provide extra ammonia and nitrite as they rot, so I don't think this is the best way forward. If you want to use a natural method then it would be better to put a living pond plant in there. Also be very careful with any nitrogen compound test kit. They are...

    Ca deficiency?

    Well, this is a difficult question to answer definitively. Scientific journals do not address nutrient deficiency in aquatic plants because the journals will only address issues that are within the context of natural environments. Quite to the contrary, scientist attempt to determine the causal...

    Ca deficiency?

    Focusing on ratios is another path that leads nowhere. The idea of using ratios to analyze plant health came from someone ascribing the Redfield Ratio to plants. Again, in land plants ionic ratios in the soil may be relevant, however, aquatic plants morphology differs significantly due to the...

    Ca deficiency?

    Is Tropica Premium Nutrition chelated or salts?

    Yes this is really odd because a member based in Holland had asked for some help regarding this. Perhaps the rules are that you must furnish the data to the governing body but that it was not necessary to list them on the label. Cheers,

    Is Tropica Premium Nutrition chelated or salts?

    No, its based on the past history of vendors who refrain from listing their contents. This is why I used the modifier "typically". It's also been our experience that when vendors refrain from listing their active ingredients, it's "typically" because the ingredients are easily obtainable and...

    1.5 PH Swing / 0 KH

    Ca deficiency?

    This is exactly why it would be best to abandon the Ca deficiency idea. Ca deficiencies are almost a myth as the plant does not not need much of this micronutrient at all. This is a CO2 deficiency. I can only speculate that the reason it has not reared it's ugly head previously is because the...

    Water flow in the planted aquarium?

    Yes, it is a known plant food, and that is great in a low tech tank, however, in a fuel injected tank the breakdown of organic waste is also trigger for algal blooms. Besides, we are already feeding the plants with nutrients, are we not? Cheers,

    Question Gh and Kh planted aquarium

    Hi, Yes, sorry, that's wrong. The micronutrient metals are normally "chelated", which means they are chemically bonded to other compounds. Even so, the reason the metals are called "micro" nutrients is because the plant only needs microscopic amounts. You never have to worry about Prime...

    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.

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

    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...

    Hello, You only need to add any dechlorinator at water change time. This is very easy. Make sure you use a product that neutralizes chloramine if that is shown on your water report or if it is unclear. Normal chlorine will dissipate after 24-48 hours, so many people will store water for...

    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,

    Water flow in the planted aquarium?

    Hi, 3D backgrounds make things worse by disrupting the flow patterns in the tank. The best one can do with these, if removal is not an option, is to cut a slot so that the powerhead can be made to fit above or below to maintain the straight on angle. The next best thing is to mount it on the...

    Does Mg lower KH?

    The reefer is wrong in his words but is right in his concept. This is yet another example of poor choice of words causing confusion which leads to misconception. Folks on this board bash me for correcting their words (which they consider insulting) but the reason I persevere is specifically to...

    activated carbon

    This is not really true at all. This is a boogie man story programmed into our psyche in order to frighten us so that we will continue to remove and buy more product. The fact of the matter is that there is no physical or chemical reason for the substances that were adsorbed by the carbon to...
