Turnover Calculations

[D'artignan]

Hello Everybody,

New to this forum, and loving it! So, I know there is a thread already about pumps and turnover rates. But I have been having some trouble with the calculations. I have a pump that pumps 800 L/H(211G/H?). My tank is a 15 Gallon... If calculated correctly. The dimensions are 60cm - L, 30cm - H, 30cm - W.

If my calculations are correct, I have a turnover of 17. Please help me out on those calculations... Also, if the turnover really is that high, how can I reduce it?

Thanks!

Some pumps come with a valve that you can use to throttle them down. If yours does not have one then you can always get a small pvc valve and attach it somehow to do the same thing.

Otherwise, you can probably make the pump work as is by creating a good distribution of flow with a good and long spray bar.

What kind of filtration are you going to run using this pump?

Thank you! I constructed a DIY canister filter with a sump. I will be running that

What size sump?

Also, just so I have this right, are you overflowing into the sump and then using your pump to pump the water through the canister and back up to the display tank? If so, what is the head height between the surface of your sump water and the surface of your display tank?

I am using the natural water flow to run the water through the canister, and into the sump, from whence the pump(which also contains a sponge filter) is pumping the water back into the tank. Unconventional, I know, but I like testing the boundaries

Oh, looking at 90cm head height.

Only issue I see here is that any canister will eventually clog up a bit. When this happens your tank will not be able to overflow, or at least not enough and then you will have a lot of water on the floor. I recommend you move the canister to be placed on the return line so that the pump can pump the water through it and you don't have to run the risk of overflowing your tank. Also, with that pump, you might be needing a larger pump so that you have enough power to push through the canister and up the height to the tank.

You're making this way harder than it needs to be.....with a 15 gallon tank.

The traveler whom sticks to the road less traveled, bears no risk of seeing what other travelers have not seen before him. But, out of curiosity, what would be your personal recommendation for a 15 Gallon's filtration system?

Thank you! I will bear this in mind. I appreciate all the feedback.

I would put two of these on it if I were you. I have two of them on my son's 10 gallon tank. Just use sponges in one for mechanical and ceramic rings or some other form of good bio media in the other. They work very well, are easy to clean and are quiet.
