Well I've had my QT (6' POP tank) setup for about 8 weeks now, but I can't seem to get the nitrites to drop. Here's the vital stats:
PH 8.0
Nitrates .25
Ammonia 0
Nitrites 2.0 +
KH 10 drops (190ish)
I feed almost nothing, water changes every 3rd day or so, clay every other day (1/2 tbp), filter - KW sand filter (55g), + 55g SC half filled with buffer pad. Total ~500g or so. Load 50 3" tosai 1 16" asagi (asagi recently added). I've kept the salt @ .3+ for the duration, and the fish seem great, very active. I just don't know why the ni won't drop. The wc's seem to do little to nothing for the nitrites. Is it possible to have a filter that can handle the ammonia but not the nitrites?
Any advise will be greatly appreciated!!
Thanks, Chris
