The one thing I would do differently is?

[Northreef]

1) Taller stand so my sump/skimmer can be accessed easier
2) Spend the $$$ up front and get the light you want not just what you can afford as you will end up buying it anyway
3) Research everything!!!!!

Best of Luck!

Just started 3 months ago and built my 90 gallon tank into the furnace room. Looks great from the rumpus room but is difficult to clean/vaccuum/ scrape algae. Also, taller stand would have been ideal. I did put a sink with running water in the furnace room and also and left the floor concrete for spills, etc. The cost wasn't an issue for me because I researched things for over a year before I decided to go for it and knew it was going to be expensive.
