I don't have any tests yet. But here is some pictures
Pictures of the sump area
What is going on with that chaeto?
What do you mean?
More of the refugium
Why is it out of the water
Haha it's not. That's a float refugium. The water level you are seeing is the water flowing around the refugium. I pump tank water into the refugium and the water from the refugium drop into where the scrubbers are.
I'm going to venture a guess that due to the clean sand and coralline, that P is coming out of the rocks in spots. And thus, nutrients are flowing into the scrubbers. And the chaeto is dying in the inside slowly, and supplying many more nutrients to the scrubber that just the rocks would, and thus the scrubbers are dark. In other words, the scrubbers have found a lot of easy-kill with the chaeto, and are being flooded with a high flow (not high level) of nutrients.
So I would remove the chaeto. Scrubber should then get brighter green, and, growth on the rocks should increase even more in the same spots as the P comes out even faster.
I am starting to get algae on my sand too. You just can't see it from the picture. But regardless I will remove the cheato and see what happens. I kind a want to try a cpytic zone anyway.
