    I have been dosing with Potassium Nitrate (KNO3) Potassium Phosphate (KH2PO4) and GH Booster. I'm mixing;

    3tsp KN03
    1/2tsp KH2P04
    1/2tsp GH Booster
    500ml Water

    I'm pretty sure that the GH booster is the one NOT dissolving into the water, I have tried tank water, tap water, boiled water, all with the same result, sediment in the bottom of the jar after an hour or two.

    Any idea's?

    Hi Johnny,
    I think that's just life with GH Booster. I think it has Iron Sulfate and Magnesium Sulfate in it, both of which have lower solubility than the nitrate and phosphate salts. If I'm dosing GH Booster I normally would just put a pinch in the tank after water change and let it go at that. Maybe someone else has a clever idea. In any case, could you not just shake vigorously and dose the mixture? After a while whatever you dosed will dissolve.

    Cheers,

    Ok, cool, I just shake the mix and dose, doesn't seem to be a problem, just wondered why it was doing it.

    Cheers,

    I always have problems with the Equilibrium I use with my RO water dissolving very slowly, however I find that RO Right dissolves almost instantly so you could switch to that from your GH booster.

    TBH I'm not even sure I'll keep adding it, I was adding it after advice from here, I could dose MgS04 instead. We have very soft water(0/1kh)
    Whats RO Right?

    Cheers,
    JOHNNY

    See here

    RO Right's a powder to remineralise RO water. Bascially it adds magnesium, calcium and a few other things. Basically it does the same as your GH booster.
