turnover on 180 gallon

The Saltman · 03/11/2007, 08:44 PM

Hi guys,

I have a drilled 180 gallon tank. The overflows are rated at about 600 gallons per hour each. If I get an external pump to handle this, I'm only turning over the system about 10X per hour. How can increase the turnover?

I appreciate your response

I guess, the question is, if I use a sequence pump, such as a hammerhead and use a manifold to use the returns as my main curculation, will the overflows be able to handle it?

You should target 3 - 5x display volume via the return pump. A lot depends on how big the sump is and how it is configured.

A hammerhead is a 5800 GPH pump. WAY too big.

I was looking into a mag 18 if I was going to run it inside the sump. What this be fine?

I dont like big Mag pumps. How big is the sump?

The Saltman · 03/11/2007, 09:31 PM

Sump will be acrylic around 50-60 gallons

I think an Eheim 1262 would be good if you want to do an in sump pump. It will get you ~ 700 - 750 GPH which is ~ 4x turnover. It is extremely reliable and very quiet as well.

What do you like better about the Eheim pump versus the bigger mags?

sjm817 · 03/11/2007, 09:42 PM

WAY quieter for one. The large Mag pumps also need very large plumbing to get decent flow out of them which is often impractical. I dont see an application for a 1800GPH 150w submersible pump. If you wanted that much flow from a return pump (you dont), you should use an external.

i use two mag 12 with one inch lines on my 150 flow is great no noise

sjm817 · 03/12/2007, 06:24 AM

The 1" lines are cutting the flow back a lot.

The eheim also uses alot less watts and run's at a lower heat. If you want some more circulation look into some powerheads or wavemakers. I'd suggest the hydor koralina 4's 2-4 of them. 1200gph each at 49.99-55 bux.

I read that 1"holes although rated at 600gph, actually do about 300-400gph "comfortably". In other words, quietly.

I run an eheim1262 on my 180 and this works perfect for me.
Dead silent and cool running, perfect flow.
Don't like mags either, loud and warm.
3-5x for sump, and add tunzes or koralias for good flow.

I use a mag 18 on my 180 with no noise or heating problems at all. I have two mj 1200 mods and a koralia 4 in the tank along with a closed loop running off of a mag 7 no problems with that mag either
