Hi! I need help! In the picture i understand the water level in the overflow must be on B , but when i put it in that level reducing the pump power the return make lot of bubbles and noise, if i put the water level on A , i have 0 noise, but im not confident , looks like i can have problems if return doesnot work properly.
Any help will be apreciate, thanks.
