Hello I’m thinking of increasing the flow of the return pump on a Nuvo 40, which is the Mighty Jet 538GPH. I read that the Sicce 2.0 is a very tight fit. Curious if anyone has tried another option, for example the Aqua Illumination Axis 90 Centrifugal Pump. Looks like it would fit. But I see some negative reviews about the pump intermittently shutting off. Well thanks in advance.
