Need recommendations on filtration system

I am getting ready to setup my first saltwater tank ever. Which is the best for a 55 gallon tank? The guy who I have talked to several times this week recommends the FLuval rated for a 70 gallon tank. Any info would be helpful.

Any fluval or eheim would be fine. I would go as big as the budget allows. My salt water tank is filterless because I use the live rock as a filter. I have a 29g tank with about 60lbs of live rock. Then I just have a pump that circulates the water. 6 months in and so far so good.

Coral is growing and fish are healthy. Good luck, you will love it.

15 gallon to a 20 gallon 3 stage sump

So which is the easiest setup for a 1st timer?

I do not planning on having anenomes and seahorses when I start.

I got a great deal, so I think on a FLUVAL 305. With shipping I am paying $120. Hope it does what everyone says it does.

Is it a fish only tank ? or will you have Corals also ?

I plan on having live rock as well.

if its just fish and LR then a hang on back filter or two will work ...marineland Emperor 400 or Penguin 350
