Flow in aio cube

[cpschult]

does anyone have guidelines to how much flow they want? I’ve got a 25g aio im lagoon. Currently 1xpp-4 high middle glass. I normally have on w1, 4 strength. The “else” mode was rearranging bed.

Any help/tips? I’ve had a 125 and 70 gallon. Never had to much flow there!

From the return I would say most use 10-15x GPH. In a 25 AIO, the display is probably 18-20 gallons. For soft corals I would say an additional 10-15x GPH from a powerhead or gyre is fine and up to 30-50x for SPS. It really depends on what you keep and your substrate.

I’ve got a sicce syncra 1.0 (251gph), and the pp-4 (132-1,000 gph).

Heavier substrate, can’t find exact name but it’s not fine sand.

Hardest part is figuring out a good flow pattern in this small tank!
