    I have a new 2 feet tank. I have a box of Duplarit that is enough for this tank. Am going to mix that with Holland sand to form the first 1/3 of the substrate and to topup with Holland sand also.

    I have all the macros and TE to fertilize along the EI method. I will mostly have Hairgrass and some Crypts in this tank. And I will only dose them with Excel.

    1) What sort of lighting do I need in terms of wattage per gallon

    2) Can I follow the recommended EI dosage for a 20-40 Gallons tank ? ie:
    1/4 tsp KN03 3x a week
    1/16 tsp KH2P04 3x a week
    1/16 tsp TE 3x a week
    50% weekly water change

    3) I am thinking of getting one of the Eheim's Liberty HOB. They have 3 models to choose from:
    a) Model 2040, for tank size up to 75 liters. Output 150-380 liters/hour
    b) Model 2041, for tank size up to 130 liters. Output 220-570 liters/hour
    c) Model 2042, for tank size up to 200 liters. Output 320-760 liters/hour

    Which model is recommended for my tank size?



    Please advise. TIA.

    When you said 'part of EI', do you mean I can use half or maybe quarter of the dosage? I am sorry, at the moment I am still not a paid member.

    Ok, Here is the sum of the link.

    See the "non CO2 method" article.
    Excel is like adding 1/3 CO2, so use CO2 methods, eg water changes and some light ferts.

    Regards,
    Tom Barr

    Basically use 1/3 of your suggestion above with Excel.
