I have a 90 gallon display linked to a 65 gallon frag tank. They run at almost identical cycles (aside from ramp up/down from 1200-2100) time. I am wondering if off setting the light cycles of the tanks and running my frag tank from 0500-1400 would help to narrow the range of my pH. I use a CO2 scrubber where you see on 09APR where the media was changed out. Usually 1.5lbs will last well over a week before it starts to fall again. Just trying to prevent as many dips but not raise the pH higher than a ~ 8.4 average.
