Made a change to the sump. Don't laugh, I needed it to be reconfigurable, and may not be done playing. This is a 20" square I am hoping to grow Cheato in. I basically made an eggcrate box, and put it in front of the last baffle before my pumps in the return section of my sump. I am hoping to get a cheato ball to roll. I used some corrugated plastic to make sides and direct the flow in a way to get a gyre type motion. It took a couple tries but when I drop a clump of hair algae in there it rolls in a way I think will work. I am lighting it with a Kessil H380. I'll pick up a chain to hang the light then I just need to put the algae in. I don't currently have any cheato, but do have a couple different kinds of caleurpa I can start with until I get some. I wanted to take this step before putting the flucon in my system so I had some nutrient export while the algae is dying (hopefully) and the skimmer is off line.
