Hi all. I have a 65 DT tank with a 20high sump. DT is doing great corals all seem happy. In my sump I have a reddish color growth that holds a lot of air bubbles that is over taking everything including my Mexican caulerpa . I also have some red macro algae growing on a clip suctioned to the glass so the red air bubble stuff hasn’t gotten there. The red stuff is mainly growing on the xport bio block that I have in the sump and that is where the cualerpa is also. It used to just be green hair algae and cualerpa growing together but no all the green hair is mostly gone and it’s covered with the red stuff. I run a luxbird waterproof refugium light on a night schedule over the sump.
the first pic is the red stuff the second is the macroalge that I wanna keep growing. The third are my tank parameters as of yesterday. The only that has really changed was magnesium that was 1160 a few weeks ago and I have raised it to 1440. My first thought was to turn off the refugium light but that would hurt the macro.
none of it is in the DT at all.
any advice ??
