Just amazing, the best .
Syncra Silent v1.5
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.
Sicce Syncra Nano pump
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.
Pump is really nice and quiet however not really as strong as i thought it would be
Get it . Wont be disappointed. Impossible.
