1 what kind of filter are needed
You'll need about 75-80lbs of
LR and a good skimmer. I would go with an Aqua C Remora with a surface skimmer unless I was going to set up a sump. You don't need a power filter unless you don't have enough
LR to handle the bioload.
If you don't intend to keep corals, you could get by with two 40w normal output bulbs. Better would be at least a 2x65w
PC setup with 50/50 bulbs.
.
3 Do I really need a sump pump?
No. A sump is a great place to keep equipment...skimmer, heater, ect... You don't have to have one though. You will need several powerheads in the tank to create the needed flow.
4 Do I really need a chiller?
Probably not. The only way I can see you needing a chiller is if you installed a
MH lighting system and had several pumps adding heat to the tank. It also depends on the temp in your house.
5 Can I do this in a 55 gallon tank?
Yes.
6 what are some of the basic things I should buy?
You'll want two heaters, enough powerheads to create a minimum of 550
gph, a skimmer (
IMO), a thermometer, a hydrometer, and test kits for ammonia, nitrite, pH, alkalinity, calcium, and nitrate. You may also want to either purchase an
RO/
DI unit or find a source for
RO/
DI water. Tap water is not recommended in
SW tanks. You'll need the usual collection of buckets, hoses, ect... You'll want a container to mix your saltwater in. I use a Rubbermaid tub here. You'll also want an extra heater and powerhead for the mixing tub. I have probably forgotten a few things, but I think that covers most of the basics. I would get a copy of "The Concientious Marine Aquarist" by Robert Fenner as well...that's an excellent book that will help get you started and give you advanced info.
