I actually bought a chiller from this company called Chill Solutions. The product got great reviews. After purchasing it we upgraded my Axolotls tank to bigger size then the recommended maximum (the chiller goes up to a 30 gallon) But we never got to use it. The only thing I did touch was part of the tubing to soak in dechlorinated water, thinking I was going to use it. If you would be interested in purchasing it from me please pm me and we can come up with a price that we are both comfortable with
