Hi Ephraim , I too will be soon making the plunge after keeping freshwater for many years and dabbling in saltwater many many years ago.
Just reading the thread and understanding that your pockets are not deep ,it may be a good idea to rethink the size of your proposed system.That is one pretty large tank and as the guys say will soon bust your budget.( you will need more and bigger sizes of everything )
The cost of a tank is only a small percentage of the cost of the whole system so why not go a little smaller ?
There are some amazing medium size set -ups on this site .
I am going to start with a 30 gallon cube that I picked up from a member for $60.00.
FISH ,( chad)Has a cube currently being set up and is giving us a blow by blow account

of his progress. Don't be confused by the motorbikes at the beginning
