This is very encouraging to hear. I just scrubbed all the rocks best I could with a toothbrush and did another 25% WC. Added a fresh baggie of Purigen and another 2x amount of ROX carbon. I upped my moonlight intensity very slightly (from 1 Dark Blue to 2 DB and 1 Blue), trying to take it slow and steady. I think I might introduce a very low intensity full spectrum to the tank this weekend for only 1 hour and see how that goes.
