well i've had the original biocube protein skimmer from sapphire aquatics since the beginning, since I've started my tank back up it will work for a few days but then I'll go look to make sure it's working and it just stops producing bubbles altogether, i've cleaned it out a few times and yet it does the same, any suggestions?
