Have had RPE's for over 6 months now this is happening. Good flow, lights are T5's on 12 hrs/day. MH on for 6 hrs/day.

pH 8.3
Ca 400ish
Mg 1400ish
KH 7.5ish
temp 77-78f
no nitrates,nitrites
no phos
no amon
can't figure this one out.....
could it be due to the fact that i run lunars all night long?
could it be that i soak my filter sock in bleach to kill out the junk when i rotate them out every 2.3 days? then rinse it out with cold water for 5 mins before i replace in the sump?
any suggestions here? losing some pretty sweet z&p's to this, but only the RED ones!!!!!! odd.
