Hey everyone I'll keep it short I use to have a 37g on a cannister filter. It went well for about a year then everything died fish snails crabs everything in the about 1 week. Its been a few months I'm starting back up. I scrapped the cannister filter reused the 37 gal and built a 10gal sump with digit fiji cube baffles and another baffle set from Amazon. I'm setting up a hang on Overflow into the sump with a filter sock into mechanical filtration, into refugium and and back up. Anyones opinion or suggestion I still need to get return pumps I'm thinking 2 200gph (goes up about 4 and a half feet I Wana use pvc pipes not tubing 10 gal sump and 37 gal display) any input would be appreciated. thank you
