not sure if that's what my skimmer is called. It's the hang on back with the bubble blaster pump. I'm wondering if I can use an aquatrance pump? I bought one but it doesn't look like it can be used for a HOB.
My bubble blaster still works but I cant find an impeller for it.
The aquatrance does have some kind of adaptor included but I dont know where that goes. I didn't get any directions with it. I need it to be external for my skimmer and it looks like it's only internal.
