A decent enough choice for a 30g tank... The Prizm is very popular so it obvioulsy is doing sumthin right =) Getting the Remora would give you more long term flexability (ie. when you get a bigger and tank, and trust me, you will cuz there is no such thing as ENOUGH room...) but when the cash isn't there, it isn't there, right? Good choice for you tank...
FYI, I've read many account of the Prizm and a big complaint are initial micro-bubbles... This is common with every skimmer I'm aware of, and they go away after it get's gooped up properly...
