Aquarium Advice Apprentice
I Have a 55 gallon Fish only salt tank. Its been running almosta year now with no problems . Last night I went to sleep and the water was crystal. I have a magnum 350 canister an aquaclear 500 on the back and to powerheads. I woke up thjis morning and i cant even see the fish in the tank. I have a yellow tank 2 percula clowns a Half black damsel a blue damsel a bar goby a coral catfish and a green chromis. They are all swimmimg around fine. And my one piece of rockwith green star polyps looks okay ie the polyps are opened and out. I had the walls primed yesterday could this have something to do with it. Should i mix up a huge batch and saltwalter and do a massive change? Ive gone through my cycles brown algae than green and now red/purple algae. My levels are ok ammonia salinity pf nitrite nitrate same as ever. PLease HELP
