ive had this cube for a few months now. have a outbreak of of GHA. my parameters were all spot on. the tank is not being over fed, no fish currently in the tank on the corals, cuc, and a shrimp. i do weekly 1.5g water changes. last week i cleaned the back chambers out of any detrious. did 2days of no light. but didnt see any diff. except that it ****** off my corals. i have been doing some spot treatment with peroxide. and thats been helping. as far as filtration. i have a media basket in the back of the tank. filter sponge on top. center is Chaeto. and last chamber is purigen and chemi pure. Fitration im running a mj900 for return. and a MP10ES. Lighting is Cree Leds. If im missing anything just shot me a msg. i really need to get this under control. i dont want to resort to using any chemicals in the tank. cuz thats just a temp fix. but this is really stressing me out.:sure:
