Wetman, Thanks for the info and the compliment (I’m really into dwarf pikes). I actually got the idea of the peat from looking at your website. I believe you helped out before when I first decided to use Peat.
When I first used it, I didn’t boil it. I just ran it under hot water from the shower and then tossed it in a bucked with the powerhead. I thought that the only thing the boiling would do was sink the Peat. Which really didn’t matter to me since the powerhead would suck the nylon sock of peat down to the bottom of the bucket. I didn’t realize that it would expand the Peat the way that you had explained.
Initially I just felt weird about boiling Peat. But I’m going to give it a second shot, as I hear Water Softness is more important than the lower PH.
As for rainwater…I’ll take my chances with Peat. Living in New York, you never know what you’re going to end up with. Thanks for the help and wish me luck. (It’s been a while since any of my fish spawned

, and I’m thinking it’s the water).
