I'll be checking out that thread.
Well, there hasnt been any crossing of lines, it's a simple Water General system picked up back in April of 05. Put it together just like the instructions said. This is a rather recent phenomenon. I think I might collect the waste when I fill up my 32gal for a water change just to see how much it's rejecting. Not sure that will mean anything but I'll see nonetheless. Come to think of it, the waste line could be clogged with junk. It's set into the drain pipe from the clothes washer. Lots of cobwebs and dust bunnies in there and I havent pulled that thing out since I put the system together.
