I have had a 90 gallon setup for a year and only have a few fish and corals· I am ready to have amazing reef and fish aquarium. I have googled and you tubes and now I'm more confused than I was before. I want replace the equipment I have and start anew. In looking for advise on everything that. Will need at the moment I have to powerhead ,I really don't think that's enough flow so I would like to change out to a IceCap Gyre 3k. Should I put two in or will one be enough? I have three heaters that I have had been using for years not sure of brand. The tank has been steady at 76 -82 not sure if the change means time for new heaters any suggestion, how many and temp setting. My protein skimmer is a Sea Clone 100 . It has been pulling stuff out but its brown and watery I was told it should be thicker suggestion on new internal skimmer, would like to also change out canister filter to a sump setup suggestion? Also looking for suggestion on feeding corals I was using zooplanton, seaweed pellets, brine shrimp. Thinking of changing to reef roids, Mysis shrimp. My light was a fluvial 2.0 that has died. Temp light on will be replacing in 2 weeks. Reefbreeder v2 suggestion's on settings setup for tank . Well I think I got everything. I did have a hairy green algae bloom I got most still working on that. Also had a apptasia take over while I was away. Got most still working on that too. Oh yea skeleton clean up crew suggestions. I have 2 leather corals , patch of star polyps, Zenia, unknown coral any one know the name ? Clown fish and a purple gamma , sand sifting star fish. Please suggest away need all the advice I can get. Thanks .
