If you don't want to read it all here's the basics. Picked up a 100 gal 75 gal 80 to 90 LB rock skimmer and pumps for 140.00 I was scrolling through the craigslist adds for tanks because I have been wanting to upgrade so that someday I could keep a yellow or hippo tank. I was searching and searching and ran across an add. a 100 gal tank, half the rock in it which comes to about 40LB, sump, skimmer, return pump, and power heads for 200.00, or 300.00 with a 36" PC light. Anyway I call him up and apparently he has two tanks (the other a 75) both 200 or 300 with light. I say I'm interested in either as I want to go bigger, and we both start talking about our reefs. He says he would be will to take coral as trade also. I gave him and list and he wanted a large kenya tree, colony of anthilia, huge frogspawn, and a ric. I said no problem I'll bring them. He said Hows 100 plus the coral sound. I thought wow I already thought I was getting a killer deal and he goes down alot with out me even trying. So I drive to his house give him the coral and we get to draining the tank and loading and he says you can go ahead and take all the rock. (I'm about in hog heaven now)LOL I get everything loaded and he looks at me and says "well I only need 30.00 more for a light I have been looking at, do you want the 75 too for 40.00 more. I say wow that's a great deal but I'll have to talk to the wife. Needless to say I drove home with a 100 gal 75 gal and stand 80 to 90 LB live base rock, pumps skimmer mag7 for return and heaters, for 140.00. I got it all that cheap with out even trying. Sorry for the long story I'm just siked. Now to get them going and sell my 40.
