Sump pump size...

[hdrob]

That's great. Thanks for the reply!

If the flow wasn't too over the top I was going to go with it. Like you said, I can always Tee off excess flow back to sump. I wasn't going to drill for closed loop, but I might still do it. The tank that I'm hopefully picking up this weekend has 2 corner overflows with one hole in each overflow (hole is drilled right in the centre, no room for another hole). Just outside of each over flow is is another hole for return. So, I should be able to setup one overflow as a semi-herbie with the second overflow as an emergency drain? Or should I set it up with stockman type of drains?

I like the look of a separate 20g refugium beside the DT. I guess by using the one pump and splitting the flow to fuge and other equipment, I should be ok with the dart.

Thanks a lot.

I have 2x 1.5" returns set up as a herbie, one side of the tank is done with the gate valve for flow adjustment, the other 1.5" is the emergency drain. the flow back to the tank is done through 1.5" PVC and splits to 2 x 1.5" going into the tank(I'm planning on choking these down to 2x3/4" for some more velocity comming out of the nozzle) I've got 3x kora 4's for flow in the tank and using a dart gold pump for the return. I've got a bunch of stuff T'd off the return, my carbon/refugium are right now, and once i change the nozzle's in the tank i should have enough back pressure to put my pellet reactor on there too.

The Dart Gold i'm using has LOTS of flow, i have a dump from the outlet back into the sump to be able to change the output, i usually run it dumping about 1/4 of the flow back to the sump right now. I lost a lot of flow going to herbie, the 1 overflow cannot handle the amount of water that is needed. I had duroso before but was having problems with microbubbles.

I'd suggest going for it, i'm wasting a bit of flow right now, but saving on heat since i have reactors running off the return rather than having individual pumps.
