I made a snap decision today...
I wasn't crazy about the noise level from the Jebao DCS9000. Anything above 1 on the controller and there was a noticeable hum. The tank is in the living room, and noise level is a huge concern for me.
So... I picked up this guy:
It took a bit of figuring out to get it plumbed up. I am running 1" flexible hose for the return, split to 3/4". The outlet is 1-1/4", which I reduced down to 1" and screwed in a 1" barbed fitting.
I am filling the tank with RO/DI as I type this. I'll be transferring over my rock and getting the cycle going this week.
