hello again Hobogato....
The new tank has been up for 4-5 months now. almost everything was a transfer from the 65 gal that I had before.
Seemed to have the same issue on that one. (but I fed it a lot)
The inhabitants love the new halide lights, but I may tone it down an hour to see if it helps any.

I just hate constantly cleaning it, and wondering if messin' w' it is what's causing the issue.
