    Oxidation IRON

    Hi! Where can I read more about the processes that occur after chelated iron is added to water? After what time does it disintegrate? What exactly does it break up into? What happens to these substances in the ground? How do these processes change depending on the presence of organic matter...

    Do you mean the phosphate buffer? Can you tell us more about it?

    Plant deficiencies and the Fe Experiment

    You wrote that you switched to 50% osmosis water and therefore reduced the dosage, but this led to chlorosis. Have you solved this question somehow?

    Plant deficiencies and the Fe Experiment

    It turns out that in a planted aquarium, is it necessary to have an anaerobic zone in the ground?

    Plant deficiencies and the Fe Experiment

    Why does the presence of CO2 determine the need for iron chelation? Shouldn't it be the other way around? The higher the pH, the greater the need for chelation?

    But aquariums with soil contain a lot of organic matter and there is nothing wrong with that. Or..?

    Plant deficiencies and the Fe Experiment

    Hello, I did not really catch the idea of why manganese is washed out of the sediment and why this contributes to the production of these metals by plants. Can you explain this point? Thank you.

    Seachem method of potassium dosing

    Maybe you know..Why is there a lot of calcium in a marine aquarium, but the problem of phosphates is still difficult to solve there? There is always a lot of it and every time it is a problem

    Could you give an example of the actual operation of this equation in our wonderful hobby? For example, with the same phosphates and iron themselves..

    AS900- restart and rethink.

    Do I understand correctly that FePO4 will be determined by tests, but it will not be available to plants? Although Maq wrote that it may be affordable in the long run.. How does all this interact with soil? There is phosphate inside the granules, but since little iron is added, it does not bind...

    Plant deficiencies and the Fe Experiment

    Why is there no iron binding at a phosphate concentration of 0.1, but it occurs at higher concentrations? Why does the concentration matter? Thanks a lot.

    Ca (kH?) : NO3 and other nutrition ratio.

    When increasing the GH (kH), should I increase the micro or macro dose? I work with soft water a lot and use microdoses there (not the residual index). But when the water has a high GH level, such as 6, should I add both micro and macro doses more? Or can I keep them at the same level? I am...

    Which branded fertilizer "Iron" is suitable for hard water? Seachem, I understand, is not suitable?

    How is your aquarium now? How much do you dose fertilizers per week? I read that Manado absorbs phosphates, have you noticed any problems with this?

    СO2 I have in that tank. So. If I have high kH and gH I need dose EI and do I need to plant many plants at once like how about using soil?

    How much is NO3, PO4, K do you dose per week?

    Calcium and dosing fertilisers

    I have no problem dosing a lot of fertilizers, the only question is how much? I still have a few plants. How much do you recommend to dose per week NO3, PO4, K, Fe?

    Calcium and dosing fertilisers

    So, at high levels of alkalinity and general hardness, you just need to pay attention to iron?
  31. MiZubov

    Calcium and dosing fertilisers

    Will the dosages listed by you somehow change if the alkalinity is not 0, but 7, for example?
  32. MiZubov

    Calcium and dosing fertilisers

    Do I understand your point of view correctly? Calcium and Magnesium do not affect the dosage of fertilizers in any way, and high alkalinity requires an increased dosage of iron with the right chelator?
  33. MiZubov

    Calcium and dosing fertilisers

    Can you give an example? What precipitates at high alkalinity? It turns out that I need to increase the dosage at high alkalinity?
  34. MiZubov

    Calcium and dosing fertilisers

    Thanks! What negative effect does high alkalinity (kH) have, besides the fact that more carbon dioxide needs to be supplied and the soil is destroyed faster?

    Seachem method of potassium dosing

    What about iron? How much NO3: PO4 do you keep? How does the phosphate precipitation reaction occur? Let's say there are 0.1 phosphates in water, after adding calcium, it decreases and becomes inaccessible to plants? Or does it happen in some other way?
  37. MiZubov

    Seachem method of potassium dosing

    But what about: "Calcium is an antagonist of many heavy metals, as well as phosphorus." So, there is a precipitation of phosphate in water with high calcium and it needs to be added more to maintain the correct N: P ratio? I understand and take into account the ratio of Nitrogen and Potassium...

    Seachem method of potassium dosing

    That's what I want to understand. If I have high calcium, then I have to keep higher values of Potassium, Phosphate, Nitrogen, Iron on a constant basis. But how much exactly?

    I'm using RO water, but stones raises gH very high.

    Calcium and dosing fertilisers

    Hi! With an increase in gH (Calcium to a greater extent), is it necessary to increase the dosage of fertilizers? It is believed that calcium is an antagonist for many elements, and therefore suppresses their consumption. Is it so? If your gH is 3 and 15, will you increase fertilizers 5 times...

    Seachem method of potassium dosing

    Hi! Well..I have a problem with staurogyne repens, but I dose a really sufficient amount of fertilizers per 36l of water in a week: 2,64 NO3, 0,32 PO4, 4,48 K, 0,5 Fe and micro. But I have hard water kH 9 gH 19.. That's why I asked about Potassium, because it seems that potassium is not...

    Wow! So interesting! How did you come to this conclusion? Did you specifically testing? Thanks a lot!
  43. MiZubov

    Seachem method of potassium dosing

    Thank you. But my questions were something another: 1. If manufacturer considers it necessary to be Potassium ~40 constantly, it means there is no overdose potassium? 2. Matching Seachem with Tropica system. Thank you, but for me doesn’t matter how much cost fertilisers.

    Seachem method of potassium dosing

    Hi! Seachem recommends to keep for planted tank gH 3-6, raising it with Seachem Equilibrium. But if I use Equilibrium for keeping gH, for example, 4,5, you will keep Potassium about 39 ppm and in addition to this you need dosing Potassium during a week. Some questions: 1. Is there no potassium...

    gH in RO water

    Hi! I know, there are some relationships between Ca, K, Mg, Micro, N. This is especially important when using osmotic water. If the balance is disturbed, plant leaves and stems are twisted. When you use RO water, what ratios do you adhere to? Thanks a lot.

    PPS pro and Soil

    Hello! According to the Edward PPS Pro system, you need to support parameters like this: NO3 5, Po4 0.1-1, K 20 and so on. Question: If I use soil, do I need to maintain the same water parameters? If so, why do we need soil? Thank you. Have a nice day!

    Hello! I want to clarify about the PPP and PPPD parameters. PPF — photosynthetic photons flux — the number of photons directly affecting chlorophyll a, b and carotenoids.

    What prevents plants from absorbing all spectrum?

    This means that whatever the lighting power, chlorophyll b at 480nm will absorb 80% of the fallen light, regardless of the power of the lighting source?

    What prevents plants from absorbing all spectrum?

    This article says that only a small part of the sunlight is captured by plants, and the rest is either reflected or passes into heat and the like. The sorption of sunlight is depicted on my graph, but my question is whether these graphs change when plants are illuminated by an artificial light...
  61. MiZubov

    What prevents plants from absorbing all spectrum?

    I mean, there is a graph of light absorption by plants and each spectrum has its maximum: for example, chlorophyll c has it in the region of 85% about 480nm. This means that if 200 umol/m2*s 480nm falls on it, the plant will absorb 170 umol/m2*s, well, but if 400 umol/m2*s falls, 340 umol/m2*s...
