DCS1200 is noisy as f, i ditched it. Most quiet pump that fits in the WB mini P is the Aqua Medic DC Runner 1.3.Ok so I've learned the Mightyjet return pump sold at BRS or Innovative Marine fits. It's a great choice for the Waterbox Peninsula Mini 25G in relation to this thread. Only problem is it's only available in America and they don't ship anywhere. I would assume Mightyjet is better quality than the Jebao DCS 1200. But the Jebao is like half the price and has a similar flow controller. Except you would need to trim the Jebao down to fit.
I've been running a dead silent Aquaone 750L/ph pump just to suffice for now because the OG pump was just too loud. My tank's at my bedside and it drove me nuts. I use a Sicce voyager 2 to keep good flow.
The Jebao DCS 1200 would be my pump choice. Although before stumbling onto this thread, I had been thinking for a long while about buying and adding a whole canister filter, taking the crap out of it, fill it with bio-media and use black tubing to pull water from the bottom of the return part of the sump and attach the flow part of the tube to that duckbill water spreader it comes with. Then it's basically your standard return pump while simultaneously adding more water volume and housing more beneficial bacteria increasing the overall stability of the Nano tank. I wanted to do this on top of building a refugium with an AC110 Aquaclear HOB Filter to house Chaeto and Copepods. You could call me an equipment junkie but I just want a nice diverse developed stable tank.
It's REALLY quiet.
