Replumbing my 135 design choices

slavearm · 04/20/2006, 11:42 AM

Ok guys here it is, I am currently running a Mag 9.5 for my return pump and a mag 18 for my closed loop system. I am also using a seio 620 and 820 in the tank. My tank is a 135 with 60 sump.

I am going to go with one of the two following systems.

Option 1
Keep the Mag 9.5 (93W) for the return
Ditch the closed loop system and get a Pair of Tunze 6000s with a 7095 controller (~40W)

Total watts used (136W)
Total Water movement (~3500GPH)
Total Cost to me $750(Tunze) + 10 (Plumbing) - 70 (Mag18 sale)=$680
Other factors: Have powerheads in the tank, more heat in tank, lower power consumption

Option 2 (preferred)
Ditch the 9.5 and 18
Plumb in a Sequence Dart to both the return from the sump and closed loop. Run the return from the Dart to an OM 4Way.
(please see the image below... took me awhile to wrap my head around it)

Total watts used (~150W)
Total Water movement (~2800GPH)
Total Cost to me $220(Dart) + $320(OM 4Way) + $60 (plumbing) - $70 (Mag18 Sale) - 50 (Mag9.5 Sale)= $480
Otherfactors: Slightly higher power requirements, CHEAPER, less heat in the tank, no powerheads in the tank.

Kick me down with some feedback. Also... is the Dart a loud pump? Shouldn't be louder than my external mag18 right?

Thanks,

Slavearm

I have a 135 as well. I had it drilled for a closed loop & already pre-plumbed it out. Was debating on using CL or doing powerheads.
Didn't want to spend $ on Tunzes or use a hi watt pump for CL.
I decided doing the following.

Return pump QuiteOne pump 4000 (1000gph)(40or50watts)
2 MaxiJet 1200 w/ boat prop mods approx. 2000gph each.(23watts each)

Total flow 5000GPH less the head loss from return pump
Total watts approx 80watts.
Total cost is $110 ($50 return pump & $30 each for MJ mods)

Also the MJ mods are pretty small & look clean.

Just my 2 cts.

Good luck with your setup.

interesting idea, never seen a large return pump setup that way before where it takes suction from the sump and the tank. Will this work? I would be concerned with overflowing the sump if power was lost. A check vavle does not help in this situation.

Definitely ditch the mags cause they give out alot of heat, use too much energy - more than stated, and are inefficient. I would just upgraded to external return pump and external cl pump. Throw in a seio 1500 and call it good. Just my 2 cents.

I'm interested in this as well.

I am trying to get myself a nice wavelike motion in the tank, and I don't like using wavemakers with normal powerheads, because they die quick, and in the case of the maximod, have difficulty starting up the jets at times.

The sump shouldn't overflow. That is the beauty of the design (I think and why I included the diagram). It should only put as much water into the sump as it sucks out, because all the other water will come from the closed loop. I should be able to control the amount flowing into/out of the sump using the ball valve attached to the sump. Since the water going into the sump is from the overflow, it should never put more water in than I suck out from it. It is the same principle as using a normal return pump.
