I will check that book out if it ever gets here...

Actually I was thinking about building some of my filters and using sphagnum peat moss instead of a deer net as filtration media. It would add nitrogen to the water and also acidify my 9.0 PH. It would also be cheaper too. Those deer nets are 20 "buck"s a piece! I could save some "doe". Maybe it would be smart to make bags out of the deer net and put the peat moss inside them. I'm not sure at this point but it seems like a good idea. Who knows. Maybe I can even get the PH down enough to raise catfish.
