Rio skimmer replacement impeller help

[tigerbarb]

I need a new impeller for my rio skimmer. I found a site that has them, but I have no idea which size impeller I'm supposed to choose. I tried researching, but I couldn't find an answer. Can somebody please help me figure out which one of these rio impellers works for a rio nano skimmer?

What size is the pump on the skimmer.....

Looking at ***********'s site it would appear you would need to know the size pump to get the correct impeller.

The pump says Rio 110 HOB filter....110 GPH. I don't see that as an option....

Here's a link to manufacturer......

Also assuming the pump is a 1100....I googled Rio 110 HOB filter and came up with an 1100 HOB no 110 HOB, but here's another link as well....

Worse case call Marine Depot or they also have live chat as well......
