I have found the need for a chiller. I have a300 gallon reef that I am having to much fluctuatiion with temp. I waslooking at the Tunze super 1/3 hp. Has anyone had anyluck with this chiller or is there a better one out there? I do like how it controls the heater as well and that is what I am looking for. A plug and play unit that will keep temp stable.
