I am going to take my first foray into a reef tank. I have done sal****er
over the last 10 years with just a simple undergravel filter and power
filter.

I acquired a 55 gallon system and my plan is to purchase 60 lbs of live
rock, not sure whether to use crushed coral or sand yet...and I am looking
at the Tom Aquatics PS3 protein skimmer/canister filter all in one.

Any suggestions? Words of wisdom? Anyone have an opinion on the PS3
skimmer/canister system?
