There is info on water parameters by species, but you have to find it. With the net being like it is today...

Some of my books get down to the nitty gritty on water quality for various species, but they are in a box buried under a lot of stuff after this recent move. Gonna take some effort to dig them out.

I got this big Gaylord box from a friend and packed a lot of my stuff in it from the shop, planning to bring it home. A guy from work brought it to our new warehouse. Figured I would just go there and load it up on my truck with the fork lift. That ain't gonna happen anytime soon. This guy buried it way in a corner under a 30' row pile of junk. You have to move all that stuff to get to it and I had to climb all over this crap to even find it. Guess what he's doing next week wink
