It's big!

Comments: I have a 50 gal reef tank with minor heat issues, so when I went to look for a chiller, rather than going to a in-line chiller, to avoid the additional plumbing (canister, uv sterilizer, etc.). I wanted a drop-in style. Well, it's HUGE, the unit is big, the hose is about 2" in diam, the coil is not just 10" long but about 3.5" wide, outside diam, not including the lead into the coil, which also must be immersed. Needless to say, this will not fit into my little 50 gal, especially with HOB filter intake/dual output, HOB skimmer, etc. so I have to get a sump to place the chiller in. So I have not actually used it, as I am in the process of switching tanks and sump. I have been told by other experienced aquarists (once they finish laughing at my predicament) that this is the Cadillac of chillers, (although I don't know if they are referring to the size or the performance), and it's not the fault of the company that I underestimated the specs when looking at my tank. I have high hopes for this monstrosity, since something this big must perform well. I still like the idea of a drop in, both for ease of use as well as avoiding more plumbing.

Comments: Purchased this chiller since I was having 82-84 degree temps in my Solana XL60 from a Geisemann Infinity 250 W. Works awesome and is manufactured like a quality piece of USA equipment. I didn't want the hassle of the in-line chiller using a pump, so this fits the bill! The 1/4 HP chiller brought my temps down from 84 to 76 within 20-25minutes once plugged in. Since then, it has turned on for only 5-10 minutes after many hours of monitoring temps. The chiller is rather large and the coil is 9" in length, so I good size foot print area is needed and a decent size sump is highly recommended. I don't recommend using this chiller within an even somewhat enclosed space (heat) or an area that you wouldn't want noise. It comes with a accurate temp probe that controls only the chiller and is preset to 76 degree with a deviation of 2 degrees that can be adjusted.

Comments: Works great on my 220 gallon reef tank and the installation is a breeeze the only draw back is that the fan can be little loud(it's the loudest piece of tank equipment when it's running) . But it does cool my tank quickly so it's not on very long and the temperature stays dead even.

Comments: Although this product is rather expensive, it appears so far to be quite efficient and does not need to run excessively to maintain 77 to 79 degree temperature in my 105 gallon reef tank which has metal halide lighting. There is some fan noise, but that is to be expected and is not particularly annoying.

Comments: This chiller worked incredibly after the tank settled from over-heating. But keep in mind the fan that is inside has some serious RPMs and will make air noise. Compressor is super silent though.
