    Hi all.
    Could someone please give me some advice on a dosing regime for my tank?

    Tank specifications:
    Tank: 600 X 325 X 355 (L X B X H) 69L
    Filter: Textra EX 700 (700 L/H)
    Heater: 50W
    Lights: 1 X Dual 24W Odyssea T5 with 1 X Sylvania Grolux and 1 X Sylvania Aquastar (10000K)
    Substrate: 9L ADA Aquasoil Amazonia
    Total water volume to fill: 70L
    No injected CO2.

    Using the Fert Calculator, this is the best that I could come up with:

    [​IMG]

    I am using Richard's method as described in (http://www.apsa.co.za/board/http://www.apsa.co.za/phpbb/viewtopic.php?t=2 and doing 50% water changes per week.
    This tank was first filled 30/12/2012, and I only started dosing 08/01/2013 and is lightly planted (at the moment :laughing7:)
    I will start dosing Excel from this weekend.
    I currently only have my lights on for 4 hours a day.

    Am I on the right track with the above?
    Is there anything else I should doing/adding?

    TIA

    Why not dose ADA in such a small tank Brighty K will last you 23 weeks and Step 1 to 3 x 47 weeks that something like R70 a month only?

    or even go with tropica ferts. i went this route and the tropica is so much easier. no mad science stuff to mix and calculate and with no CO2 it just makes sense to use these ferts. just my 2c on this

    For something this small I would also go with ADA.. last long.. Go with step 2.. step 1 is too weak, it depends on the ferts existing on the soil.

    Or ELOS, if you can find it locally.

    Tropica is good, but not as concentrated.

    Thanks to all for the input.
    I will look at going onto ADA in the future.
    But would this routine be okay to start with?
    I shouldn't change every?
    My lighting period and everything else okay?

    TIA

    Hi Darryn, you are not so posed to need to do full EI in the beginning with aquasoil due to the high content of nutrients in the soil.

    That is why ADA recommends K and some traces only in the beginning!

    Sean will be able to help more on this!

    Yes, the Aquasoil leaches ammonia in the beginning stages. And the fish will provide the Phosphates when you add them and feed them.

    Aquasoil will stay nutrient rich for a long time, which is why the Brighty K and Step series is so good. You're not adding anything you don't need to the tank. I have used this personally with amazing results, and the 250ml bottles last for about 3 months on my 60L tank. The 500ml bottles last 2 and a half months on my 200L tank.

    EI is good, don't get me wrong. But ADA is easy.

    Sean is right..

    You can dose EI, but it will be a waste. If you using ADA soil, in the first few months you need just K, and step 1 (which is weaker than step 2).

    Using ADA you cannot go wrong, for something that size is the best, hence why I recommended it also.

    Just keep your light on for short period, and keep the CO2 stable, and you will be ok.
