120 Gallon Reef set up ready to add salt water and rock

Hello,

The venturi is ahead of the pump and with no salt, the bubbles are large and can cause a lot of noise in the pump. It should quiet down once you have put salt in the system.

Aspirating venturi is nice for small or valued systems. A better way of doing it is to use a real venturi device after the pump, though you need a pressure rated one then. I personally don't believe in them aspirating venturi in skimmer use as it cuts down the performance of the pump.
