Surfer,
Welcome to the site.
I suggest you start by reading this article :
https://www.livingreefs.com/articles/beginners-guide-t503.php.
This should answer many of your starter questions.
Focus on the sections 'C' through 'G'.
I am assuming you have a 29g tank, non-drilled, possibly a Euro-tank from Petco or something.
You will need some basics for starting.
The filtration you are mentioning you have is typically for FRESHWATER and will not be beneficial in a SW tank.
1.) You should have good lighting for a REEF tank as corals will require special lighting.
2.) You will need Live Rock for filtration as well as Live Sand.
Adding new liverock & live sand will typically put your tank into a "CYCLE" which needs to complete before adding livestock (anywhere from 1 week to several months).
3.) You will need a protein skimmer for removing excess waste from your water and cleaning up your overall water quality. I suggest an OCTOPUS Hang-On-Back skimmer for a non-drilled, non-sump tank.
4.) You will need some powerheads in the tank for circulation & flow. Without this, you will have stagnant water and nothing will survive. I have a 30g with (2) Koralia #1's. One circulates the water around the tank. The other breaks the water surface with a ripple to circulate water and aerate the water.
5.) You will need a heater. Your water should be between 76-80 degrees without much fluctuation. Drastic temp changes will be detrimental to your tank.
Read some of the articles on Living Reefs and ask plenty of questions.
When working with a SW tank, patience and slow progress is the key.
P.S. pick yourself up some water quality testing equipment :
1.) Refractometer for checking Specific Gravity (Salinity)
2.) Thermometer for testing water temperature
3.) Water test kit (PH, Nitrite, Ammonia, Nitrate) for fish only tanks
4.) Additional water test kit (Kh, Phosphate, Calcium) for reef tanks
Sorry about the long post & sorry about the Bucs big loss last week!!!
I lived in Tampa for 7 years and went to every game (in the old stadium).
Good Luck!
