should not be any air bubbles when return pump is on and if I shut the pump down I have a main ball valve on each manifold so before I turn the pump off i will just turn the valve and no water will drain back into the tank. Reason why i did it this way is because I want full control over each return eductor, only way I could fit valves in without being in the way. They will all be covered with a cabinet anyways.
I will be using 2 Waveline 10000 DC pumps so we will see what happens, my friends tank is the exact same design and is one of the nicest I have seen for a soft coral tank. PS thanks for fixing the pics not sure why photobucket wont work?
