flow rate to sump?

[Dragonflyx2]

I have a 10 gal sump with filter sock and two heaters for my turtle pond running @ 350gph pump.
if I increase the flow rate of my sump will that increase flitration or cause problems with the heaters and filter sock?

how high can I go before the flow rate is too high?

Correct me if I am wrong. I see that you are pumping the water from the pond into your 10G sump. Then a have a 1" drain into the pond. Quite the opposite for the usual aquarium, but understood since ponds are usually at ground level.

Now to answer your question, the limiting factor I see is the return pipe size. A 1" tube has a max flow of 600 GPH given the correct perimeters. Seeing as at 350 GPH the sump is already over 1/4 full, I don't think upgrading would be a wise idea. Unless you plan on getting a larger sump or doubling the return.

Oh, to answer your first two questions. It is recommend that you have a turn over rate of 3-4 times the size of your tank/pond. Even at 1800GPH, you filtration and heating should not be a problem. The limiting factor I currently see is the size of your sump.

What happens if the drain from the sump fails/loses siphon?

Crazyness, the water level in the sump is due to the design of the overflow thing, not the flow rate.

To the OP: A higher flow rate isn't going to cause any problems. But, it looks as if the pump would keep draining the pond if the siphon stopped working, which would be bad. You would either flood the room or the pump would run dry (maybe both)

Consider arranging the the sump so that the pond drains into the sump and is then pumped back into the pond. With a large diameter drain pipe you can drain at whatever flow rate you want. The amount of water that will drain out is limited to that volume that is above the bottom elevation of your drain line. This should at no time exceed the volume of your sump.

Put a ball valve on the pressure side of your pump line (the hose going back to your pond) BY THROTTLING THIS VALVE YOU CAN CONTOL FLOW RATE. The faster you pump into your pond the faster it will drain out to your sump. Make sure your drain line is at least two trade sizes larger than your return line.

In theory there is no limit to how much flow you can acheive this way. In practice you are limited by the maximum flow rate of the pump. Your drip plate holes total area should be three times the cross sectional area of the drain line-just to be safe.

There should be no issues with your heaters, and the higher the flow rate the better the filtration. Make sure that you don't restrict the drain line in any way. ie. put the sock on the return line if you feel you need it.

ok let me try and word this diff. LOL

if I build a 2" overflow just like the one I have.
and change the pump to a 1000gph for example.
when does the turn over rate become more then the media can handle?
as in the water flowing through the media too fast to be filtered.

or

how much of a turn over rate can I get using this amount of media?

theres a lifter pump hooked to the top loop of the overflow so that never happens.

pic is old and Ive moved it and made some small changes.
