Hello @rvitko,
I’ve had my internal skimmer for about 2 years and a few days ago I noticed big bubbles of water accumulating on the external side of the bottom plate. It looked like the plastic might have been cracked, leading to bubbles forming.
So I took it out of the tank to check and there were no cracks. I figured I’d do maintenance on it and test it again after (last maintenance was done 10 weeks ago). So I cleaned the casing inside and especially the impeller and the pump. The impeller looked okay. What looks like a screw on top was worn a bit, (I didn’t take a picture) but nothing major so I just reassembled it and put it back in the tank.
It’s been over 24 hours now and it’s not skimming as it should. Even if I adjust the amount of air on the controller, bubbles aren’t rising as they always did in the cup. Before I would turn the knob almost completely down (about 22%) because it would overflow otherwise, and it did a good job like that.
Now I’ve adjusted the knob 1 1/2 notch up but there aren’t more bubbles rising in the cup and skimmate isn’t collecting faster. It doesn’t seem to be skimming much (it looks like the same level as yesterday), and it’s skimming wet.
Do you think this would typically be a problem with the impeller itself, or the electronic controller and pump (which looks like it needs to buy as a set together) ?
Thank you.
