I have a Red Sea Reefer 900 3XL, and i am using the split sump option. I have the additional portion of the sump (bottom right compartment of the stand) set up as my Refugium, but the water flow through the bulkheads just doesnt seem like it’s enough to toos and turn my chaeto. Does anybody have any tips, tricks, and suggestions to encourage more flow through the Refugium to turn the chaeto over more?
