Hi Everyone. I ended up giving up the in wall tank idea. Now I am getting a gorgeous Oceanic 90 gallon tank. I am sooooo excited.
I was going to do SW but right now decided to get aquainted first and do Fresh water. Although this site is for saltwater, I know many of you also have FW tanks. So my question is, is this setup good? This is what they recommended:

Coralife t-5 10,000k lights 2 of them 48" $64 each
Fluval 405 - $245
Airmaster 3000 - $26
Stealth 150 Heater - 2 @ $39
Python gravel cleaner - $90

That is what they suggested to start. Can you tell me what else I should look into?

Thanks so much! You all are SO helpful. I truly appreciate it.
