how to replace impeller?

[drukkosz]

Hi i am cleaning my swc 160 skimmer and would like to replace my impeller for the modded one. But how do i take the old one off??
is there a special trick?
thanks

Just use a big flat screwdriver to pry the impeller off the magnet.

Are you replacing the impeller because you are having problems with the skimmer not starting ? Because your stock impeller still looks fine.

If you have the restart problem, just add a little plastic washer and it should work fine.

no i want to replace it because i read that the mod impeller works much better

 

[drukkosz]

that worked thank you

Make sure when you install the impeller that it actually snaps in all the way.

Is that a bubble magus impeller? Looks like one. The only way to objectively determine which is better is if you measure the air flow on the air intake using an air flow meter.

When I tried a bubble magus impeller, I noticed I had to raise the water level of the slimmer, which means the bubble magus impeller was pulling in less air.

yes it is bubble magus, i will give it a try for few days and see how it works. I dont know if its just me but i think i have less micro bubbles in my sump now.

the bubble magus impeller is rated 500L/H air flow while the SWC impeller is rated 650L/H air flow and I believe that is accurate rating. air bubbles would be less if you adjust the water level higher. If the impeller pulls in more air, you would need to adjust the water level lower and result in more air bubbles in the sump. that should not be a problem as the return section baffles should remove the micro air bubbles.

I just got a used 160 SWC and the original owner said the impeller had to be replaced. took off the old one and the new one is smaller and does not clip on. Is it ok if its lose or is it the wrong one?
