It's yours Scott! Great idea
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.
