I am starting a waterbox 60.2. It’s a 40g display with 20g sump. I am having a hard time pulling the trigger on a return pump. I plan to have a mp10 for flow and and for return pump am considering a reef octopus varios4, ecotech vectra S2 or maybe going for an ApexEL with COR15. Not sure how much I like being soo reliant on the apex if I go that route. Any suggestions or guidance appreciated.
