A skimmer is a worthwhile investment.I was running a g3 asm and switched to a bermuda 3-c what a difference a skimmer makes. Spend some money i have a 55 gallon also and the bermuda is bulletproof.The best part about the bermuda is you are not limited to what type of pump you run no special pump to buy. I run mine on a mag 7 but any pump in that catagorey will do the job.
