I see it's extremely difficult to get responses in the forums. I guess i'll continue to try and figure this out myself. I mean temps are steady between 77-82 during the day with sun outside and CFL's glowing. pH is all within range, juss changed the res so Idk whats going on. I'd ask for suggestions, but it seems that may be a lil far fetched lol I'll keep trying to diagnose the problems, and i'll let those of you out there know he cares to read what happens. Thanx
