Flow question for new tank

[sirburke]

Hi.

I recently started a new tank (getting back into the hobby after a very long absence) and I am having a bit of a flow issue. The tank is a 55 gallon that came pre drilled with the xaqua in and out which aligns with the sump from eshopps at 600 gal/hr. I have a Coral Box 6000 running at 20% and the return is a bit less than 4 feet up.

if I slow the return, which I could do with the wave pump compensating the sump gets higher than it is supposed to and I believe I would need to add water to the system since the drain starts to gurgle.

At 20% I very slowly lose a little ground until the a kicks in and refills the return chamber.

with that background I have two issues...

The slow loss at 20% in the return chamber and a waterfall sound in the overflow which makes me think I should add more water to the system and boost the speed of the return pump to create a better siphon.

Thoughts?

Are you able to adjust the height of your drain.

Are you able to adjust the height of your drain.

do you mean. In the sump or the tank. I can cut the shot down spout into the sump and make that shorter but the drain itself is fixed in place on the back wall of the tank.

In your tank most of those behind your overflows are adjustable.
