The primary function of my sump is:
increase water volume(additional 15-20 gal in my case)
location to run skimmer(EuroReef CS6-2)
means of circulation which allows for removal of powerheads from the display(I run approximately 1200 GPH thru my sump and back to the display via 3 returns)
Means of feeding water to my refugium(I run a large refugium from my sump with about 100 GPH flow rate(I use a ball valve to regulate the flow)
Remote location to perform water changes/drip additives.
