Sorry Marie, I always mix my additives with fresh water and then add them to my sump. The sump always needs to be topped up anyway. Usually when I add calcium I add a bit at a time but in the past I've loaded the tank with heavy doses with no ill effects. Assuming a heavy dose on 65 gallons is 40-50 mL.
CaCo2 is baking soda (sodium bicarbonate) and CaCo is washing soda (sodium carbonate). This is the Alk additive I add, a 6:1 ratio raises Alk without effecting Ph. I used a 7:1 ratio last night to try and lower my Ph, because thats what bakin soda should do. Should these be mixed separately then added? Because I usually mix them together.
Ever since I bought the bucket of IO salt I've had nothing but problems!
