We have two 29 Gal. Biocubes which are about 2 months old and were cycled using about 30lbs LR and 20lbs Live sand, and used "Stability" to aid in the cycle.
Tank 1: Older style cube, using Biocube filter cartridge and a DIY media rack with Chemipure and Carbon. Stocked with several assorted SPS and LPS corals, 1 sm Yellow Tang, 1 Damsel, 1 Starry Blenny, and 2 sm Percula Clowns with Lg Rainbow Anemone. Clean up crew consists of a few Hermits,Turbo snails. Nitrates= 80+ppm
Tank 2: New Biocube, using Biocube filter cartridge and Bioballs. Stocked with a few LPS corals, and several softies like Toadstool, Xenia and Mushrooms as well as 2 Picasso Clowns with 2 sm RBTAs, 1 Diamond Goby, 1 Lawnmower Blenny and a Potters Wrasse. We feed both tanks every other day with a small amount of LRS Reef Frenzy. Nitrates=40ppm
Both Nitrate levels are the highest they have been since we started them. PH is 8.0, Ammonia is 0, Nitrites is 0. We have been doing 30% water changes every week with RODI water and "Reef Crystal" Salt.
