Hi all, i have this sump that im not sure if its efficient. I wanna make the best of the equipments i have so i was wondering if i should set this up any other way? I just feel like my system is missing something, but not sure where to start. I just want my livestocks to be as happy as possible. My dt is a 75g and this is abt a 20g sump. Overflow drains on the left, then its the refugium, and finally skimmer w return pump at the end. I couldn't fit the skimmer in the first chamber
. I've thought about swapping the return pump and the overflow drain but didn't know if that would be effective enough to try. Any help would greatly be appreciated.
