Hi everyone! I finally have my new tank filled with water and I'm running just the water pump to mix the salt. My problem is that the drain hose into the sump (1" hose) seems to have air in it and gurgles incessantly. Is there anything I can do to reduce this? I've tried moving the hose around in the hopes that maybe the bubbles will flow out but it hasn't worked. Any help would be greatly appreciated. Thanks!!!
