softies and skimming?

[Rippin]

I'd love to help you, but I can't read graffiti.

Really, unless English is not your first language, or even your second, would it kill you to spell correctly and use proper grammar?

On your 33g a nano skimmer may do the trick. Beyond the four Chromis', are you planning on any more fish? Fish can produce a lot of waste. A skimmer would help if you have a large bio-load.
Try going skimmerless for a while with weekly water changes and see how it goes. If your fish and/or soft corals looks like they're stressed, then a skimmer may be in order.
