    Solufeed 2:1:4 and Solufeed Sodium Free TEC or Solufeed Coir TEC Combination

    @mow said you can use either one of the Micros, But I would go with the Tradecorp AZ and you can decide weather you want to keep the Micros and Macros separate in their own solution. I also Recommend using Distilled water for solutions. we can add Magnesium to your aquarium during water...

    this will work fine as well. but you didn't answer the following: "ok lets start with your tank, how many gallon or liters is it going to be? then your solution size for Micro and Macros? 500 ml? then how many ml per dose? 10 ml, 20 ml?"

    "PPM or Parts Per Million is a unit used to describe very small concentrations of a substance in a larger solution" EDTA and DTPA are not the same, they both use different way of Chelation and DTPA is more stable overall, EDTA uses Ethylenediaminetetraacetic acid while DTPA uses Pentetic acid...

    I believe we may be having a language barrier, possibly due to translation if that is what you are using. ok lets start with your tank, how many gallon or liters is it going to be? then your solution size for Micro and Macros? 500 ml? then how many ml per dose? 10 ml, 20 ml?

    micro and macro dosage

    TDS has nothing to do with this, even though higher TDS generally mean higher GH/KH etc. but the primary issues are related to PH/KH when we refer on using chelation. there is no issue mixing a different chelation of Iron together. I believe you are not fully understanding how this whole...

    micro and macro dosage

    Vinegar doesn't fully preserve the solution, while it may kill or prevent some of the mold/bacteria. Potassium Sorbate will preserve the solution to much high degree. Vinegar primarily lower the PH and acidify the solution. for most Micros, chelation isn't necessary. Fe and Mn may require the...

    micro and macro dosage

    if you are using the above then the Micros/Fe and Macro solution are kept separately, I only added Potassium Sorbate. White Vinegar is fine to add along with potassium Sorbate. most of the time I no longer use Ascorbic Acid for my projects.

    These are my standard. I target N as Proxy for my Macro dose, so it could be anywhere from 1-3 ppm N weekly. However, I never feel the need to exceed the Micro dose of 0.1 ppm Fe weekly as Proxy, regardless of weather I dose 1 or 3 ppm N. RO water Mineralized to: CaSo4: Ca 10 S 8.0006...

    Yes, the water usually had 0-1 dkh and 2-3 dgh, I often change the dgh to see the response from the plants, but dkh is always kept close to 0. Fe will be influenced if the dkh were to be high and may require changes. but, K can be kept within the same range.

    Solufeed Coir TEC contain DTPA Fe, which itself is highly protected from the Phosphate interference. we further add some vinegar to acidify the solution to lower the PH which keep things more soluble and protected.

    1-3 ppm K weekly and 0.02 - 0.1 ppm Fe weekly. the point is that low tech tanks would have far less of an uptake and the needed nutrients.
  25. Happi

    Low-Tech Fertilizer Recipe

    usually only topping off the evaporated water, in low tech tank this may vary. but 25% water change every 2 week should be good, which is about 50% water change every month. you maybe get away with less than that.

    How to get RO water to the right gH and kH parameters?

    If whatever Kyle said is true, then we still don't need to use seachem equilibrium and sodium bicarbonate to boost GH and KH. You still have a better option which is Cacl, CaSO4 and MgSO4 for GH and KHCO3 for KH, but again this will also raise the K to significant number. Sodium isn't essential...

    How to get RO water to the right gH and kH parameters?

    @Jamsim It's best to use combination of CaSO4, CaCl and MgSO4. while CaCl is highly soluble compared to CaSO4, it also adds excess amount of Cl. If I were to pick Cl vs SO4, I would rather have SO4 in little excess. But everyone have their opinions. Am not a EI user but your Potassium is...

    am not gonna lie but NH4NO3 is one of the best Nitrogen you could use for aquatic plant, even the NH4Cl or (NH4)2SO4 cannot replace it.

    Remineralisation solution precipitate

    when you Mix MgSo4 and Cacl together, this form CaSO4 in the solution and since the solubility of CaSO4 is extremely low, what you are seeing is an insoluble CaSo4. your best bet is to use MgCl and CaCl if you want to go with the Solution Route, they both are highly soluble.

    Calcium and dosing fertilisers

    I believe this was already covered on your other thread here #64 Iron is the Major one that is highly affected by such scenario. if you were to use Fe (II) under high KH, you will find that it is rapidly precipitated. EDTA, DTPA etc. can be used to maintain the Iron levels under high KH water.

    One important thing to consider when we are talking about consumption of Nitrogen is to consider weather it's coming from NH4 or NO3, or both. NH4 is rather rapidly consumed, especially the floaters consume it very quickly in comparison to NO3. If most of the N is coming from NH4, it will...

    Is my Iron DTPA solution precipitating or growing a film?

    Is my Iron DTPA solution precipitating or growing a film?

    I think you are confusing this with Pentetic acid.
  62. Happi

    Is my Iron DTPA solution precipitating or growing a film?

    no need to acidify the DTPA Fe 11% Solution, it will drop the PH to 4.0 or so by itself when added to Distilled water (don't use RO water). the only thing you should add is Potassium Sorbate or Sodium Benzoate only if you are planning on keeping and storing this solution for several months.
  63. Happi

    PH vs KH

    @Gorillastomp you do not have to dose any N and P in your discus tank if you had been doing that. You only really need to dose small amount of Fe/Traces/K daily if possible or every other day. This will resolve some of the stunting issues by itself.
