we needed them threaded thats the reason for the brass nozzles. We talked about it with the a guy over at the LFS (who does actually know a ton about salt water tanks) and said that for what we'r using them for it wont be a problem.
Jacovan1: Like pled said, i'd need a chiller to do that and also a bit bigger bank

Tanklove: Your correct everyone here is great, they prove that you dont have to agree 100% with some one elses ideas so still be useful.
Loaded the display tank up with about 25-30lbs of sand yesterday, the baffles are still drying in the sump and i think we'r going to get the sump running tomorrow.
I ordered 10lbs of driftwood base rock and 20lbs of live tonga rock on friday but i dont think its going to be shipped out till monday.
More rock will be added shipping charges were just getting a little extreme.
The baffles in the sump gave way yesterday after holding water and sand for about 30 minutes so i had to run out and get new sealant, i'm hoping the other stuff was just a little old and the weather had ruined it.
I'm going to be in Cali for five days and im leaving thursday at 3 am so the rock most likely wont be here before i leave, so when i return i'll post pictures of it.
