So I've cleaned this pump multiple times and I can figure out what's wrong with it. It'll turn a few times or once and then stop. I've research and people are replacing the ceramic with plastic but my pump appears to be different cause I can't get the bottom ceramic piece out and the top is already plastic. Any ideas or anyone have this problem and fix it? If you have this small version for sale I'll buy it too, this has been perfect for my 8g cadlights tank and my sps are very angry without it.
