Share 'SLO or External Standpipe - Fish Tank to Swirl'
I know that an SLO is the standard way to get solids laden water from the fish to a swirl filter, BUT, would an external standpipe work just as well?
I am planning on a fiberglass/wood 500 gallon tank leading to a vortex filter made from a plastic 55 gallon drum. Water movement is planned to be 10 gallons per minute.
A 2" standpipe cut at the desired tank level would be inside…
