Need higher volume return pump.. Whats a good one to use?

So, my current return pump is a whopping 2500L/ph and i just had a look at the amount coming through the drain pipe into the sump, and its like trickling. I'm not happy with it, i want it to be gushing water into there and i want some sort of ridiculously huge turnover rate.

So, in saying that.. where is a good place to buy a return pump, would a pool shop or bunnings be the place to go? I know a LFS is just gona charge a ridiculous amount for one so i'm thinking somewhere more industrial might be the go.

Any advice is appreciated.

Check out utility pumps at Aquariums R Us. These pumps need not necessarily be submerged in water (ask to be sure) but can be free standing (with a bit of extra plumbing) and rate from 1500l/ph to 7500+l/ph and range from $60 to $195.

Our good sponsors Age of Aquariums sell a similar, but not same, product. Model JHQ-5500 rated at 6800l/ph and costing $110.

Have you cleaned your hoses lately - this might help especially if you are using clear PVC tubing. The build-up of algae on the inner walls causes little eddies all along the inner surface, making the water momentarily tumble and flow back on itself, this action greatly retards the flow of water as it has to nearly travel twice as far to come out at the other end.

Yes, the lines are fine.

I've decided to run two tanks and two sumps off the same pump so i'm now looking at something around 8000 - 10000 lph and the two sumps will be drilled and using all pvc plumbing.

I'm going to have to get off my butt one of these days and check out a few irrigation joints and see what they have. I also had no idea Aquariums R Us had pumps at all. Interesting..

Pool pumps and agricultural pumps are rather costly and chew up a lot of power and it's also recommended that they don't run 24/7. Your best bet would be to run 2 utility pumps side by side, going from two 25mm outlets to one 40mm outlet via a Y junction or T piece making sure the 2 outlet pipes from both pumps are the same length using pool fittings. This setup would be far more cost effective.

As far as being cost effective, doesn't bother me because i don't pay the power bill.

I want it to be one whole system, which is why i wanted one pump otherwise i would of just had two separate tanks / sumps. Also if i have two pumps and one cuts out or decides to only be 50% working like my current pump has done in the past, the whole thing is going to overflow somewhere. One pump makes it 10000 times easier because then you don't have to equalise everything.
