I'm not proud or happy about this. But I am asking for guidance. My DT looks great. Especially after adding new lights and rocks. However...my sump or more specifically the refugium has been looking like this for a very long time and it's got me concerned. In the picture below you can see how overrun it is with algae. My chaeto seems to be doing nothing except being another surface for algae to grow... and it's all got me worried that something bad will eventually happen. I feed once a day in the morning and it's usually gone within a minute. My refugium light is always on and it's an 6500k Aqualighter Nano that the LFS
said would be great for my fuge. I haven't seen any growth or benefit for a month now.
Everywhere I look people say that this is what a sump is for and just clean it out every so often. But I have pods
/amphipods that I don't want to wipe out.
My nitrates are at 10ppm according to API master test kit. But my phosphates are 0. I read today that this slime can hold phosphates so test kits won't be accurate.
I'm looking for guidance so I can correct this problem or if it's even a problem at all. Thanks.
