I am really up in the air on a filter. My Penguin Bio Wheels are too nosiy for my bedroom (waterfall noise) even with the tank level and filled up. I was told go to an Emperor but I am seriously considering a canister. I looked at the Eheim Classic, JBJ Reaction, and the Rena API Filstar XP. I like the ease of set up on the XP. My biggest fear is leaking. I have heard so many issues of leaking but also tons of good feedback as well. I know many times user error can be to blame. What do you guys think?
