I am upgrading to a 21 gallon sump and hope it will fix many of my aquarium problems which include
1) algae growth on rocks
2) reduce nutrients in water
3) prevent infection
4) reduce water changes
5) Also I want to make a refugium in the sump and add copepods.
I am definitely asking for too much, does anyone have advice on sumps?
Upgrading to a bigger sump will only fix #5 and nothing else imo.
