I killed my whites, reduced my blues, and cut my photoperiod back to 5 hours. Tonight I'm going to remove the rocks and scrub them w/ a toothbrush out of the tank in clean SW, then spray peroxide and let sit for 7 minutes, rinse in clean SW again, siphon sandbed, replace water in DT and return rock. Lot's of work and I hope it produces results. I'm also dosing 1 ml/10 gal 3% peroxide every 12 hours when lights are out and covering the tank for all but the 5 hours the lights are on.
