I have a big problem...there are very large amounts of tiny bubbles coming from my return into my tank. No it's not my skimmer cause i shut it off and still there are bubbles. Not coming from my drains cause i put a sponge in to stop excess agitation. My pump is not sucking in air from the water in my sump being too low. The valve to my calc reactor is shut off. Im at a loss. Could my sea swirl be sucking in air somehow? Please help......
