Hello all, relatively new to saltwater tanks- I’ve been keeping freshwater for about a year with pretty good success, my first saltwater reef tank is a Coralife Biocube 32 gallon, using the coralife protein skimmer, 265gph pump, and 265 gph powerhead, working on a UV skimmer. Started off with an aquaculture clown and cleanup crew, added a Royal Gamma, a Coral Banded Shrimo and a few damsels after another 2 weeks... started to get Cyanobacteria, did water changes/siphoned off the cyno after breaking it off the sand, still got out of control, researched and used Chemiclean according to the instructions, with about a 75% dose... added a large air pump and air stone- lost all fish except the Clown within 12 hours. Removed dead fish and performed a 40 percent water change, clownfish died after 2 days, performed another 40% water change and added a large bag of activated carbon. After a week, 10% water change, added another aquaculture clownfish, died after 3 days.
Green powder algae takes over the glass completely in about 10 hours.
All inverts appear to be fine throughout this issue.
Water test results all optimal, PH is slightly low but within acceptable range, phosphates under .1 ppm per API master test kit and API phosphate test kit. Do I need a more accurate phosphate test kit?
All corals are thriving and growing.
