DIY ADA Ferts

Discussion in 'Aquarium Fert Dosing' started by Tom, 18 Jan 2008.

  1. Following on from the discussion about brighty k (and making your own from Pot Carbonate), I am wondering if I can imitate all 3 ADA ferts I use with powders? Brighty K seems easy enough, but is it known about the concentrations of each substances in Step1 and Special Lights or have ADA kept it a secret?

    I'm guessing the Step1 is just micro's, but if it differs from Step 2 and 3, the concentrations would be useful to know.

    If Brighty Special Lights is just N and P, to what ratio would it be? (10:1?) And how much would you add for, say, 500ml R/O water to keep the doses the same?

    I'm thinking I'm going to try this when my ADA runs out, and use the same bottles I'm using now as I think I've got the dosing more or less spot on at the moment with ADA.

    According to the ADA catalogue;
    Step 1 has lots of trace elements and some iron
    Step 2 has trace elements and lots of iron
    Step 3 has trace elements, iron and potassium

    The only guide to amounts is that it has one circle if they're present and two to indicate higher levels.

    K has lots of potassium and chlorine neutralizers.
    Lights and Shade have Nitrogen, Phosphate, Potassium and trace elements.

    It doesn't go into any more detail than that in the one I've got.

    This has been discussed in detail on APC.

    ADA won't release their exact ingredients/compostion. Can't blame them really.

    The Steps get progressively more concentrated, as the aquarium matures and some of the substrate nutrients get used up.

    The smart move would be to use Step 3 all the time, just less qtys, at the start. Save some ££.

    I think Tom Barr is analysing them and will publish results on his site.
     
  4. OK thanks.

    I think i want to get the powdered ferts rather than ADA because of price, but judging on my last attempt with EI I'm nervous :lol:
    hence thinking I might be able to to it in "ADA doses" which I can do :rolleyes:

    The key with EI is cram full of weeds at start up and religious 30ppm CO2.

    Plenty of 50% water changes if you see algae.
     
  6. I think my problem was, as you say, not having lots of plants at the start (big open foreground) and inconsistant CO2 more than anything else (500g bottles that ran out every week) :( I'm going to have another try starting monday and see how it goes.

    All you have to do it run a test.
