Hey all. I have a cpr hob refugium. I had it up with sand, some rock and macroalgae. After about 2 months it started having tons of aiptasia which I never seen in the dt, and the algae and red slime on the part where the water goes back in was getting crazy. I did try to cut back on thw light and it helped with the alage part. I want to put it back up, but whats the best way to make it succesful? How much light and for how long is good for the macro? And would a blue uv light placed by the intake part in refugium help at all with anything?
