Comments: Excellent ! A+++++++++

Comments: Only reason it is not 5 stars is that I have only had it a month. great footprint, quiet, does not generate as much heat as mt ond flow through chiller. only thing is getting used to the hose and routing into sump.

Comments: cools down our 300 gallon saltwater tank but cannot keep in cabinet under tank. it heats up too much then raises the water temp. need to figure a way to keep outside the cabinet but keep coil in subtank. otherwise very quiet when running.

Comments: I was at first disturbed by the lack of carrying handles and the light-duty plastic cover. But this unit was made to be put somewhere, not be a load-bearing appliance, and not moved often so a robust cover is unnecessary. I have bought other chillers which had done away with covers entirely simply to built sturdier carry handles... but this unit excels where the others didn't - it is so much quieter!

Comments: No muss no fuss need I say more? It took 1 minute to set up. Drop it in my sump and plug it in. Oh yeah I had to set the thermostat which took one more minute, So I lied ... ;-) One last thought my 175 was cooled in about an hour. From 90* down to 78* Did I mention it is so quiet I didn't think it was running compared to my old chiller

Comments: This chiller was super easy to install and cools down my 200 gallon system (175 display) by 2 degrees in about 15-20 minutes with 2-250W MH and 4-54W T5s. This is with a room temp of about 72. As others have noted, it is not quiet. When it comes on, it is the loudest piece of equipment going on my tank. I can hear it running from the next room. But having read the other reviews, I was expecting this.

<br />I am using the optional temperature controller. I have a Neptune Aquacontroller III but with the chiller, I am close to max amps on a single Neptune DC8 so decided to use the temperature controller. The controller is only good for a chiller or a heater not both. It displays and lets you set only in whole degrees, not tenths, so for these to reasons, it is not ideal. Had I known this, I would have bought the chiller without the temperature controller. I am going to switch over to use my Neptune Aquacontroller III for temp control which offers much more flexibility and accuracy.

<br />Overall, I am pleased with the chiller. It is small and discreet, solidly built, it chills quickly and the simplicity of the drop-in style is exactly what I wanted.

Comments: I recently started up a new tank using two 250 watt HQI lights and had a problem with the temp rising quickly. I have a 90 gallon tank. I didn't want more pumps and tubing in my sump, so I went with a drop in model. I picked this one and it works great. It's hooked up to a separate temp controller for both heating and cooling. This model comes with a temp controller, but it's only for the chiller. I think it works better having the chiller connected to the same controller for both heating and cooling. This model drops the temp a degree in about 15 minutes. I'm very impressed with how well it works.

Comments: The chiller cooled my 210 gallon aquarium very nicely. I installed it in about 15 minutes. The plastic enclosure is very cheep and rattles. I siliconed the handles to the plastic and used double sided foam tape to isolate the housing from the base and that cured the problem.

Comments: This is our 3rd chiller for a 125 gallon reef tank with metal halides.
<br />This is by far the quietest. Easy set-up. Be sure to really measure your sump to make sure it will fit. Must get with the temperature controller.
<br />Not real fancy, but works well, 1 degree per 30 min with lights on and QUIET!!!!
<br />Very satisfied
