Approximately how much peat in *volume* is in a gram, 5 grams, etc.?

Just trying to create a nice, homey environment for my apistos and other dwarfs : ), while at the same time, trying to leave *some* nutrients in the water for the plants, although supplemental fertilization is also necessary. > In the meantime, consider that at least there's a ready proton donor > available for the ammonia - ammonium conversion... Plus, keeping the pH lower keeps any ammonia present from becoming even more toxic as at higher pH levels. But then again, your comment is probably the reason behind that.
