Sry for a VERY delayed response. I am using chemipure temporarily in the 3rd chamber w/ the pump to battle cyano.
In the 1st chamber I have cheato and some feather caulerpa with a 10W "fountain light" over it. In the middle chamber I've got LR rubble stacked to the top and my heater.
HTH, LMK if you have more questions.
Oh BTW, I'd look into SRS (i believe) adjustable surface skimmer. Better than the JBJs because you can mount it then adjust it when needbe.
I'd look into removing the CC slowly and using sand
