I have a guestion for everyone. I have a coralife super skimmer. It is using a needle wheel pump. The pump is starting to act up and not producing foam like it use to. my guestion is can I do away with the needle wheel and use a different type of pump? I placed the skimmer in my wet/dry filter water level is alittle low for a needle wheel pump between top offs and water changes, but worked good when water in sump is at the right level.
