"tiny bubbles..."

[TANGOMAN]

I first thought my water level was low as well. I have a five gallon reservoir fed via a float valve and that was "all good". I did open the output control valve a bit to increase my flow. Cutting back flow to its original position didn't fix the problem either. This pump has always made a "clattering" noise as if it had air in it...?
I'm going to use a "rubbermaid" sump and run the pump submersed this time around. A pump dissmantling and cleaning is overdue anyway. I hope that by running with the pump submersed I don't experience heat problems though. I guess I'll worry about that come August...
