Ok lets clear some things up here.
Live rock is a BIOLOGICAL filter. You need to have at least one of each filtration type: mechanical, chemical ( skimmer ), and biological. Filters should be added, very important in bigger tanks. With a fowlr
a canister should suffice. If you do want to go witha wet/ dry filter than by all means go for it. But for a fowlr
is not an absolutely must have. You could even get off with using a hob
but i really suggest the canister. With some tanks like a reef with only inverts and some little fsih, if any at all, little or no filtration may be used but with a fowlr
tank 90 gallons and up your going to need something that'll suck up all the waste and uneaten food. Personally I would save my money and skip the wet/dry filter.
Sumps also aren;t needed but like stated above help out a little and are an optional peice. There are many skimmers are out on the market and theres no definite one to buy. SOme like the coralife needle wheel skimmer, some of the nautilus', and bak-paks are commonly suggested. Me and a lot of other people say skimmers are a type of chemical filtration. I really suggest them if your going to keep a lot of fish. It gets rid of unwanted nutrients and protiens in the water before they go through "the cycle". It also helps get rid of the gunk on the top of the water.
I would go with at least power compact lighting to start out with for these reasons...
1. Helps in preventing unwanted algae.
2. It looks good.
3. If you do want some photosynthetic critters than you can get some lower lighting ones instead of going out and buying another whole new lighting system. Get a better idea on your tank and be positively sure if it's going to be a fowlr
. It may change a little in the future but it prepares you for what may happen later on. If you think that you may get some lower lighting photosynthetic criiters like shrooms
than I would definitely get the power compact.
Don't start out with metal halide for a fowlr
. There is absolutely no need for it in a fowlr
and will really add on to your bill.
Sorry about my typing but I can't type to save my life today lol.
