Pump is solid little pump.
This pump is very quiet and does not take up much space for the volume of water flow produced. It works perfect with my MR10 reactor. I use the valve that came with the reactor to dial it down a little bit since I am running carbon but I do occasionally open it all the way to flush the lines and give the carbon a good stir.
Did not perform as advertised spyglass media reactor needs 100 gem, pump states max 110 gem, pump would not fluidize media even without any restrictions
I've got this little pump in a sump under a large vivarium. The pump powers a waterfall & stream. Head is about 4.5 feet. Pump is plenty strong, so I installed a tee and ball valve to divert about half the flow back into the sump, instead of the vivarium. This is with the pump's built-in flow controller already cranked all the way down. I expect to get a long service life out of this machine, as I'm not overworking it. Biggest plus of this pump is the noise however - very little noise. I'd buy another of these in a heartbeat.
I bought the Sicce Syncra Nano pump in conjunction with the small Spyglass Reactor kit. I use the reactor as a Purigen fluidized bed reactor and the pump provides more than enough flow to fluidize the Purigen to an ideal level 1/2 to 2/3 up the reactor chamber; it can blow the Purigen out of the reactor but flow is dialed back with the inlet ball valve supplied with the kit.
