I've tried numerous things to get rid of this rust colored algae on the white sand. I've done practically complete water changes several times. I've changed every filter in my Rodi unit. I've changed filters all together. I've reduced lighting. I've reduced the how much I'm feeding the fish. While nothing seems to be dying in the aquarium, including the corals, I don't know what else to do to get rid of this. Few weeks ago I use the red slime remover and while that seemed to work for the immediate time, everything came back. I even removed 80% of the rock work thinking that this would dramatically help. I vacuumed the sand each time I do a water change as well.
In my opinion I've done an awful lot I try to eradicate this issue. While my RDI unit has a meter to check the water going in and out my test kits for the saltwater aquarium have expired and I need a new one. Other than the kit that I need to buy, I'd rather not for a bunch of money at it and try to get an opinion or two from the community as to why this continues to be a problem. Thanks for your help in advance.
Also, I'm running an oversized skimmer in my 37 gallon, as well as filter with carbon and GFO. I have the return of the filter creating a gyre that's visible.
