Koi Forum • Nexus 310 set up with a sieve?? : Koi Talk
To use 1 pump only, you have to site the nexus about 6 inches higher than max pond water level, and return the water via 4 inch pipe under gravity only.
Can’t see the point on a sieve and nexus TBH, especially on a 310 with the eazy lid and overflow pipe, it’s either sieve/bead combo or nexus only IMO.
