I have a chiller that i used on my old 125g reef, i would have to check to see if its big enough to handle the new tank. I will have to read up a little more on pots. Glad im not in a hurry to put fish in yet (lol). Ive been adding to the tank as i go, when you get a tank that big everything doubles in price. Still need a skimmer yet, and thats about $400.00, got lucky on the live rock, only 100lbs came with the tank, i found a guy that was selling everything out of his 180g, he had 250lbs which i bought for $400.00 i also talked him into a 1700 gph pump with the deal. looked at marine depot and that pump sells for $300.00 itself. I bought the tank, stand, live rock, $700.00 in lighting, pump, and 90g sump for $1200.00. When i setup my last reef tank i had about $6000.00 in it so im trying to look around for deals this time. Have 4 kids to feed now, and a wife lol. Thanks alot for the replys and hope i didnt bore you with my project.
