    Best way to raise GH/KH in a heavily planted tank?

    I'm in complete agreement with Darrel. When I see post like these I cringe because newcomers will inevitably read this stuff and will start worrying about things that absolutely don't matter at all, and that's when they get into real trouble because their attention and energy is spent on useless...

    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...

    Water flow in the planted aquarium?

    Hmm, OK, wow this sounds very complicated. I always prefer the simpler approaches if I can get away with it. A popular general approach with sumps is one of first, covering or otherwise sealing the sump against gas leakage and then injecting CO2 directly into the sump. A major disadvantage of...

    osmocote, how much ?

    Hi, The concentration can be anything you want, low, high, Astronomical - whatever you choose. Were you aware that ADA Aquasoil has approximately 100X EI concentration level? It just doesn't matter. This is not something to worry about. The idea of having a rich sediment is that you can be...

    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...

    Water flow in the planted aquarium?

    Hello, It might help to provide some sketches as it's not really clear what the geometry you are thinking of/ If you have a center overflow box at the back then using two spraybars on either side will be fine, but it means you have to think harder about how to distribute CO2 to the...

    osmocote, how much ?

    Wow, I speak really excellent Vietnamese! Anyway DuyHung, the idea is that when you push the ice cubes deep into the substrate the ice melts and the nutrients are released into the sediment. If the nutrient content of the sediment is high then yes, some nutrients wil find its way into the water...

    Wallichii substitute!

    Hi, I guess it's necessary to define what you mean by "truly high light". I reckon a PAR value at a certain distance below the surface is the best way to go. I mean really, a lot of T. Barr bashing goes on but have you never seen his tanks? You cannot pick and choose examples of supposed...

    Wallichii substitute!

    Good plan. You can even float the plant at the surface for a few days to allow a better transition. Many don't realize that in the natural habitats, plants are not just dunked under water. The rains come and the plant has the ability to adjust to the submerged state as the water level rises. We...

    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...

    Mate, to be honest, I wasn't even aware of this myth until I read the OP. I wonder if folks are confusing wallichii with macandra? R. macandra is one of the handful of plants that are reported to struggle in high KH. Of course, people are so lazy and cavalier when it comes to...

    Wallichii substitute!

    Hi KirstyF, It's exactly as you say. Yes this was one of my tanks and nothing special was needed other than the realization that CO2/flow/distribution are the most important factors in any tank. The more light that you use the more critical these factors become. I would avoid...

    Lighting decision

    Any diy root tabs?

    I agree with Hufsa, in that no one necessarily "needs" root tabs as long as the water column is being dosed. Of course, it's always better to have nutrition in both the water as well as in the sediment, but as mentioned, root tabs often contains ammonia as their source of nitrogen and if the...

    What settings for non co2 low light plants with AI Prime freshwater lights

    Hello, In all tanks, but especially non-CO2 tanks, lighting should be very low to begin with, probably 20% power. When you dump plants under water they have the priority of avoiding being drowned. Their physiology has to change in order to deal with the water. After a few weeks they can...

    No, sorry, high pH water has nothing to do with the free CO2 in water. This false doctrine persists despite all the obvious evidence and information to the contrary.

    I'm Unsure Which Direction To Go In..

    Any supplementation of CO2, whether by gas or by liquid should automatically be considered high tech. This is completely untrue and you are strongly advised to avoid this critical error made by many hobbyists. Less light is better. Learn to grow plants with the light that comes with the tank...

    Getting desperate with my new setup, plants dying

    Hello, Melting plants are a typical symptom of CO2 deficiency. The higher the light energy the higher the demand for CO2. You may wish to reduce the intensity even more, perhaps down to 25%. Another thing you may wish to try is to move the CO2 diffuser as close to the intake pipe as...

    Some signs of Algae

    Hello, Apologies for the confusion. As far as plants are concerned the expression "poor CO2" always means that there is a problem with the ability to capture an to process CO2 from the water column. Plants can virtually never have too much CO2, however, the animals tolerance of CO2 is...

    Sunlight and background color?

    I agree with mort in post #10. Sunlight causes algae only when CO2 and nutrition are inadequate.

    Dry ferts outside UK

    Hi, It's really not necessary to find any special supplier. Any garden center usually will sell KH2PO4 and KNO3, as well as micronutrient mix. Farmers have been using these generic products for a very long time and we have been using them for decades. If you have access to Amazon or ebay...

    Tropica specialized on RO water.

    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...

    Phosphate in tapwater

    Hi, Yes, in the EI scheme of things this is normal. One of the reasons is that much of the PO4 is re-used in various metabolic cycles, whereas generally, the N from NO3 is consumed to a much greater extent by the construction of components such as proteins and so forth. Phosphorous is...
  41. ceg4048

    Phosphate in tapwater

    Yes. No. Add as much PO4 as you like. There are no repercussions of high PO4, only of low PO4. There is no "Goldilocks Zone". Required nutrient uptake is a function of light intensity, temperature and nutrient availability. It therefore changes as these variables change. Fretting about high...

    Hi John, No worries mate. I understand that we all are trying to get a grip on cause and effect. OK, I can see why some may suspect Fe (either in excess or deficiency) since there is a possible issue of Iron Phosphate precipitation. I'm paraphrasing from Barr's conclusion here: If...

    phosphate with EI - higher than 3 ppm?

    GSA is caused by any combination of poor PO4 and poor CO2. If you are adding the EI target amounts of KH2PO4 then it is unlikely that low PO4 is a factor. One then has to evaluate CO2/flow/distribution. EasyCarbo=CO2, therefore poor CO2 has to be under immediate suspicion. If you are only...

    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,

    Hardness & algae

    Heater question
