Just set up my first tank

Hello, I have finally decided to get my wet with an aquarium after considering it for a couple years, and I wanted to introduce myself. I decided to go a bit simple for now, and grow to a bigger tank after confirming it is for me.

I set up the following today and plan on adding 2 Damselfish and a live rock tomorrow:
29 Gallon Tank - Saltwater
Carib Sea Aragamax Select Saltwater Sand - I rinsed this in a clean 5 gallon bucket about 5 times before placing in the tank
100 Watt Heater
Hanging Power Filter

Any advice is greatly appreciated!
