I am selling my Aquanetics 1/4 of a HP in line Chiller. I bought this a while back from someone on this forum but found out that I will need something more powerful so unfortuantly I'm going to have to sell it off. The unit is in great condition and I have tested it out on a 90 gallon tank holding my live rock and it works great. Just be aware that I would not go above a 125 gal tank if your tank has metal halides multiple pumps and have a stuffy apartment. I'm asking for $300 and the unit is way too heavy for me to ship so it will be pick up only in Queens NY. Thanks for looking!
