ATB 840 v1.5 HELP PLEASE

Sold4JC · 01/13/2011, 01:50 PM

I came home last night to a tank crash. My return pump failed causing my main display to have a massive temp drop because all the equipment is in the sump. I repaired everything and got my temp back to normal but my skimmer has been useless. The skimmer is pulling 22 watts but the bubbles are large and violent. The tanks salinity is 1.26 the temp is back at 78 but the skimmer is doing nothing. I have been running WM bio pellets for several months now if that would add to the issue. I have taken the pump apart and everything looked good. There are no broken pins on the red pinwheel. The skimmer shaft isn't broken, the pump magnet is clean with no cracks or scratches. Here is a video of what the skimmer chamber looks like. Any help would be greatly appreciated

Does the magnet/impeller assembly spin freely on the shaft? Did you check the air feed line and volute inlet for buildup?

Aren't you supposed to turn the adjustment shaft so the two dots are further apart to raise the water level in the column?

Then there's the thread around here about makign sure the pump and skimmer body is separated by about an inch or so.

Run some carbon looks like something got in the water

I've been running carbon along with water changes and the skimmer is coming back. I really thing it was the leathers and hammer coral that slimed real bad causing the skimmer to freak. Thanks for all your help.
