Sorry, pH was 8.
Yes, we just recently lost 6 snails and we are down to maybe 2 crabs left.
There was one "dead zone" where two rocks had fallen over and I left it be for about 3 weeks (just being lazy, I admit it). That could very well have been what started all of this. I've now taken those 2 rocks out and it's an open area now. Flow is moving through there now.
All my rock work is out away from the wall. I have two powerheads, one pointed up at the surface, one about mid tank level flowing in the opposite direction. The filter flow is pointed at the back of the tank to keep things stirred up back there.

So...now I'm off to sleep. Back later...
I'll read all your posts again later with fresh eyes and after the night shift foggy brain has cleared, LOL. Thank you for the links too. I'll read those too.
