Hey reefers, its cold now but summer is coming and I am selling my chiller. I used it 1 year and have not needed it since I put the sump in the basement. As the thread title states, it is a Coralife 1/6 hp and made for any tank up to 90 gallons. It has a built in digital controller that monitors and controls the temperature. I paid $591 and would like $300 OBO. I have my receipt and owner's manual for it. I am going to post a video of it in operation as soon as it is uploaded.
