I set up an aqueon evolve 8 to replace my fluval edge. I have 3 types of mushrooms and a small rock with some green star polyps. I do not feed the tank at all.
There are no fish or inverts in the tank except some brittle stars that came in on the mushroom rock.
About a week ago I noticed a brownish green snot like algae growing. I did a water change and got all of it out. I also noticed some green moss like algae on the rock with the polyps. I couldn't get that to come off the rock.
Tank is cycled and has been for a little while I used sand and rock from my larger tank and the rocks that the mushrooms come on.
Sorry it's so long I'm just stumped as I have been doing weekly 50% water changes. Since the algae showed I do small ones through the week to remove the algae that reappears the day after I remove it.
I use ro di
water I make it myself and have a tds
meter that reads 0. I use instant ocean salt and my other tank is algae free. Any ideas on what is causing it and how to remove it?
