Return Pump Help

[Clink51]

new tank setup with a 1.5" drain that modifies to a 1" drain. return is 3/4"

I am looking into the Jabao DC 6000. i'd like to add a manifold for Carbon and GFO. Would that be enough, to much, or not even close to enough?

thanks all

IME, these pumps lose a lot of rated flow with any kind of head pressure.
I was running the larger Reef Octopus 1st gen Bio-Pellet reactor for a long time with a Mag7 pump. When refilled with 1500 ml of pellet, the Mag7 didn't quite tumble the pellets well so I bought a DCT 6000. It's better then the Mag7 but I definitely would not say that it's pushing anywhere near 1500 gph.
So basically what I'm saying is: go with slightly larger like a DCT 8000 especially if your going to manifold the output.

DCT 8000 sounds good. Any one else have recommendations? maybe other DC pumps?

these dc pump are weak, go bigger, you can always dial down if needed. My tank size might be different than yours, running 180g with two 3/4 return. Return kind of weak with manifold for gfo/carbon and a pellet reactor, pellet hardly even tumble.

go with the new dc15000 works great

i have the older version DC 9000 from jebao, just setting up the tank and loving it. I definitely dont think it puts out the GPH that it says it does, but im happy with what it does. I am able to run it at full speed which claims to be around 2400 gph and i have the same drain that you described, 1.5" pvc becoming 1" to get through the bulkhead. My return line is a full 1" though. I would definitely say the bigger the better though. Leaves more room for expanding off with manifolds and you can always dial the pump back and use a ball valve as well.
