Sump Set Up Problem!

[bollands]

hi there

after filling up both display and sump and getting salinity and temp to the right levels i have found a few problems with my set up,
the first is that the stand pipe cannot take down as much flow as is going into the tank. to solve this i think i need to restrict the flow going into the tank.

secondly the outlet is in the middle of the water. this creates a problem when the pump is turned off back flow occurs. and fills up the sump and then to the floor! so i was thinking i either need a non-return valve or an extention on the pipe to make a spraybar above the water line.

my return is a fluval fx5 and the tank is a vicenza 260 using the two holes in the bottom.

thanks for ur advise in advance.

How big is your drain bulkhead ?

How big is your return bulkhead ?

they both go down to a 25mm pipe.

An inch down pipe should be more than enough for 2500LPH is there anything restricted the downflow through the canister?

 

[bollands]

no but this is the least of my problems the most is finding a non return valve any ideas?
Although i think having a spray bar is easiest and best.

any one with a sump got any ideas?

i plan to solve the slow downpipe with restricting the output to the display

Hi - In the middle of my first tank setup too, kind of the same issue? Well, maybe. My sump drain seems too loud, and it got louder today as I changed the return pipe slightly. Swapped my custom 90' bends for a smoother Ehiem 22mm pipe.

Doing that has increased the flow LOADS, so the sump drain is now louder than it was before - and it was loud before that... back to drawingboard for me, but maybe sharper bends on the return might help you out? I can't control my flow rate on the Ehiem 1262.

Good luck.
