Re: What size Lilly Pipes for Eheim 2026 Filter If both the inflow and outflow are 16/22 mm, then you use the 17mm Lily Pipes = Inflow: V-7 17mm, outflow: P-6 17mm.
But for the 90-P I recommend an Eheim 2217 because the inflow is 17mm (so you'd use Lily Pipe Inflow V-7 17mm, which fits fine) and the outflow tubing is 13mm, so you use Lily Pipe outflow P-4 13mm. This P-4 13mm outflow is the prescribed size for a 90-P. The 17mm outflow (P-6 17mm) is a little too big for the 90-P. |
