Title: how to remove impeller
Post by: Viggen on April 17, 2007, 15:21:40: I was looking at my ER skimmer attempting to redirect the returns on the 2 pumps & I noticed 1 of the pumps was not working close to what the other one is so I removed the pump & attempted to remove the impeller & the dam thing will not come out.

Any thoughts on how to remove the impeller?

If you would like to see pictures on how to do this, go to the euro-reef website, which provides step by step instructions (and other useful info on how to maintain your skimmer, etc).

Good info Tim.

Seriously though, I will check out their site. Usually the impellers just pop right out but this dam thing is crammed in there. Not sure if calcium would be my problem because it's a FO tank. Should I still soak it? Do I just go get any normal vinegar? Dam, going to stink up the house :)

Earlier today I removed the shaft that goes inside the impeller & unfortunately I cannot get the dam thing all the way back in.

White vinegar works well.

I use white distilled vinegar as well to remove excess calcium deposits on pumps and other equipment but it doesn't sound like calcium is the source of Viggen's problem (IE, he is not adding calcium supplements to his fish only aquarium). Once the impeller/magnet assembly is stuck, the only way to remove it is with needle nose pliers.

Post by: Viggen on April 18, 2007, 21:20:14: I just removed it with pliers, I was worried to do so because I didn't want to damage the impeller. It came out very easily, it's just being a PITA to get running. Now I turn the pump on & I have to bang on the dam thing to get it to work. Plus the magnet has some gouges in it, not sure if that is causing the problems.

I am debating on finding a replacement non ER impeller & making a meshwheel for the pumps, suppose to perform better that way anyways :)
