Sicce return pump micro bubbles

[SaltReef]

Hi everyone, I just upgraded my fiji cube aio return pump to a sicce silent 0.5. Since upgrading the pump I am seeing a lot of micro bubbles coming out of the return nozzle. Any advice on dealing with this would be greatly appreciated!

I think your water level is a bit too low in the third and final chamber which causes the water to fall a bigger distance than it needs to which cause bubbles in the last chamber

Thanks for the suggestion, I’ll give that a go
