I've been shopping all over the place (random LFS's, craigslist, ebay, amazon..just to name a few) for used tanks. My most recent find is a 180 gal acrylic tank for $475, which includes a 40 gal sump and a 35 gal ref, a pump (1/15 hp dolphin) and what I think are a couple of powerheads (mag 7 and mag 12?) correct me if I'm wrong.
What I'm confused about is the number of holes in the back of the tank. It has an overflow on one side of the tank but there are four more holes, two next the the overflow and two on the opposite side of the tank.
I feel silly for asking, although I know I shouldn't. I'm completely new to saltwater. I would've posted this in the newbie forum, but I thought more people might see it here.
Here's some pics of the tank. The stand looks kinda icky but I'm not worried about that, should be easy for my bf to fix-up. The man that's selling the tanks took the pics for me when he was in the middle of cleaning it...he said to "please excuse his mess" lol...I thought I would pass that message on to you guys..
