I have a 1800 gph mag drive now....it just dosent push the water out like I want...I have a 3600 gph mag coming is that to much? the tank is recommended at 2400 but I think we can get alot better flow and cleaner with 3600?

I have a SEN700 POS right now. haha. Does the job though I guess, a little noisy.

Of course, there has been a lot of discussion about GPH through your sump and matching your skimmer and all that. I've started a few threads and polls on it before. Running 3600GPH through your sump may be way overkill and could suck your microbubbles from your skimmer right into your tank. If you really want water movement, run a CLS or powerheads. You'll be alright with the 3600GPH throttled back a bit with a ball valve but it's still a lot of water through your sump.

mine just dosen't have much flow with the 1800 I figured with double that it will run through the sum twice as much and clean it better?

we have 4 seio 2400's right now....so you think the 3600 is a overkill?

tashier · 09-15-2006, 10:58 AM

Are you running anything else for flow? Powerheads or CLS? I wouldn't depend on your returns for your total flow in the tank. It's just doesn't really work. I was going to do the same thing with my sump but realized it wasn't the best idea. That 3600GPH pump would be great for a CLS but overkill for your return.

4 2400 gph seios as well....2 maxi powerheads in the refuge

tashier · 09-15-2006, 11:07 AM

Wow, you've already got 50x/hour in your tank. You still think you don't have enough flow? I didn't realize you had a 210. That 3600GPH should be good throttled back to what your overflows can handle. You said 2400GPH. What kind of skimmer are you running? Some people believe in matching their return with their skimmer rate. I started the thread/poll above to see how many people actually do that.

Also, if you're wanting cleaner, a bigger skimmer is the ticket, not more GPH through the sump. As long as your return is at least what your skimmer rate is.

we have 2 250 gallon coralife skimmer

Hendersonracing · 09-15-2006, 11:12 AM

the flow rate on the skimmers are 500gph? so the 3600 return is way to big looks like?

tashier · 09-15-2006, 11:13 AM

Ya, just check out that thread I posted. There are people on there running 3600GPH through their sump with a 1800GPH skimmer. Probably be fine and add some more flow to your tank. I personally don't try matching my return and skim rates.

Ive got a mag 12 split for return and for chiller. Then I also have a genx 40 for the closed loop
