Sump size?


New Member
Starting my journey with saltwater. I have a 55 gal tank, 48 1/4”L 12 3/4”W 21”H, would a 37 gal tank, 30”L 12”W 23”H, work for a sump?

It wouldn’t be ideal because of the dimentions . A 20 gallon long would be a good choice for a 55. It has A large enough volume (it won’t be full, maybe 12-14 gal), it will fit under a 55, and most important it is shallow so you can access it For maintenance.
