After draining my FO tank, scrubbing away all the algae for hours, then refilling it with freshly mixed water, I've finally added sand, LR, and all the equipment to have a reef. The tank is 55-gallons, contains 50lbs live sand, 60lbs mixed LR, 10 lbs base rock. For equipment, I have the CSS 65, Jalli 216watt PC lights (2 x 10000K and 2 x actinic), CPR HOB fuge with small Jalli PC light, 3 x MJ900 powerheads, and a marineland stealth 200 watt heater (79 degrees).
