By animate, do you mean anenome?
See if you can get an overlfow box made for you tank or make one youself. I use a CPR C-Siphon overflow CPR CS90 DX Overflow with AquaLifter Pump, Class A 2nd - eBay (item 390023947115 end time Mar-14-09 14:26:50 PDT)
I personaly use only a big Protien skimmer that sits in my refugium , get one of those, a refugium that is. They are pretty easy to make from a 20g tank and some acrylice from home depot. Be sure to use aquarium safe silicone. I get it at my lfs
. Here is a vid of how to build a sump/refugium YouTube - Reef Tank D.I.Y. Sump part 1
sooo easy. This is the plan that i used.
Powerheads are always good to have. Look for a Koralia. I love them.
Lighting: Since you plan on setting up a reef tank (one with corals), I would suggest you go all out and get a metal halide setup for the tank. Coral just love this lighting and thrive the best under it. Talk to your local hydroponic store for this stuff (cheaper than the fish store). If that is a little too much out of your budget,wich it is for most, go with a High Output T5 light with actinic bulbs. You can grow a nice selection of corals with those.
You should be able to get this in any good pet store. Look for varying pieces. Pieces that you can use for the base, shelves, making caves, that kind of stuff. Be sure to bury the pieces that are going to be the base in the sand so you don't have avalanches caused by critters digging around. Be sure that it is cured live rock.
Don't use tap water, use RO
water. Considerably cuts down algae blooms. Buy a cheap portable unit off e-bay for under $80. Or get at healthfood store by the 5 gallon jug. Good luck filling your tank like that.
Salt mixture. I use Instant Ocean. Great stuff. Make sure that whatever salt you decide to use, that you can get a steady supply of. Not all salts are mixed the same. Switching salts has been known to shock and kill fish.
2 weeks? NOT A CHANCE!!
This will be the hardest part of the set-up, the wait to put fish in. If I were to do it all over again, I would wait a good 2 MONTHS!. For many reasons. 1,fish should never be used to cycle a tank. 2, it would give any parasite or whatever that is on the rock that was in the pet store tank a chance to die off if they need a fish host to survive, like ICK
. 3, you would be able to sleep good, knowing that you have done it the right way from the beginning.
Most importantly, DON"T RUSH THINGS! The more time you take to think thing over and research, the better the quality of tank you will have. Remember that you will have this tank and the fish for years to come if you set it up right from the beginning. Another useful bit of info is when buying equipment, get bigger than what you tank size is. For instance your tank is a 55g, get a heater and skimmer rated for something twice that size. The heater will have to work less, therfore lasting longer, and the skimmer would be able to process the water easier. Hope all this helps. Take a deep breathe, it takes a lot of planning, even more research, and even more money. If you are a handy person, you can save yourself some money being able to build your own surface skimmer and a sump.
