Hi, I have been fighting an algae in my tank for over a year. It is a green/brown/red algae that grows on my rocks, sand and has killed all of coral in my tank. I do water changes, blow the algae off the rocks and a day later everything comes back. I have already done a complete teardown of my tank a year ago and the same issues exist. I have added a more snails and a conch and they won't touch the algae on the rocks.
My tank is a 25 gallon with an AI Hydra 52 that is on 8 hours a day. I run Purigen, carbon and filter floss. I run a skimmer sometimes too. Livestock is only a Clownfish and Royal Gramma that I feed frozen mysis once a day. The only coral left in my tank is GSP that has stopped growing aggressively. I use RODI water for water changes and for my top off.
What should I do from here? I have tried dosing microbacteria, razor and others but nothing has worked. I'll attach pictures of the algae below.
