However, soaking > the peat I have in water yields a pH of roughly 4.0! I think the key here is "bagging up". I'm not sure what an AQ300 is, but I'm assuming it's a filter of some sort (I'm a sponge and UGF kind of guy. Ask me what a hydro-sponge is and that I can handle.). It's been my experience that when peat is placed in a nylon stocking or bag, the water doesn't flow through it. If there's some way to just lay the peat in it and then put some kind of screen over the outlet end of the chamber, I think you will get much better results. I use old-fashioned box filters in my smaller tanks. There is a volume-ratio issue as you suggested. Depending on how hard your water is, it may take HUGE amounts of peat. Then it becomes necessary to do an RO or DI solution before the peat. Perhaps you can get a 55 gallon barrel somewhere, dump the entire 40-lb bale of sphagnum into it, then top it off with water, and stick an aistone in the bottom. Then you wait a week, and start using this water for water changes until you get water parameters you want. Keep topping it off until the peat becomes ineffective and then replace the peat.
