[QUOTE=randyl;1835065]- Get a tall vase,
- Fill it half full with dry peat moss bought from garden centres (make sure you get fertilizer-free type).
How much did you actually add? i have a twenty gallon tank, and my ph is at 7.8. i would like for it to be around 6.4-6.8. i will be adding peat to my biowheel carbon filter, where i am taking out the carbon and replacing it with the peat. how much?
