[colsoscar120]

Hi guys built my sump all plumbing done return pun and overflow . I drain seem to b to slow to reach return pump is my pump to powerful or is it my overflow box . Any advice would be appreciated

Can you give a little more detail? Pump type, overflow type, drain and return sizes, etc.. I'm leaning in to the pump being too powerful.

Agreed with above more information helps but sounds like pumps to large for overflow rate.

Pump is Aqua one 3000 . My tank is 450 litres and 150 litre sump. Over flow box is reef octopus max flow rate 8000

Which pump would u suggest ?

 

[ReeferBob]

What type of drain are you running? Full siphon?

 

[jcdeng]

did you install a flow control valve on your return pump? That will help greatly to adjust the flow to match the rate of the drain.

I have and overflow box with a valve attached to overflow with pvcu pipe

Does that valve quicken the siphon on my overflow

 

[colsoscar120]

Could it also mean my baffle is to high in drain chamber

OK you just have a standard hang on back overflow. They don't have much of a flow rate. You will need to put a valve on your pump to crank it back until it equalizes.

You need to put a tee inside your overflow box to break the siphone otherwise it will drain very slow.

You need a valve on the pump only, not on the siphon. The only siphon that warrants a valve is a full-siphon, which you do not have. Your pump (return) outflows your siphon (drain), therefore you need to cut back on the return flow to equalize the rate. A valve allows this to happen.

You should plumb in a gate valve for better control but a ball valve will also work.

Thanks for you help what sort of valve and how would I fix it to the pump. Will the valve slow the pump down then
