How much purigen for a 24g tank?
I see that purigen comes in 100ml bag or a jar of 250ml and larger sizes. 100ml will be too much and the size of that bag it comes in will not fit. How much of it should I use in my 24g aquapod?
they say 100ml is good for 100 gallons so will just 1/4 of what comes in that bag work?
