"I would call that a win."

It took me a few days slowly turning the dial up to finally get it where I wanted. I have it set to 81F to get a 77F water temp. Checked the accuracy of the heater with an infrared thermometer. You program it for temperature you want your tank to be. Temperature is slightly off by running a little warmer. The heater is easy; turn the dial to set temp and plug in. The suction cups are large, high quality and seem to stick great.

PULACO PL-168 Final Thoughts

"What a long."

It just cycles through to 93f and starts over. Bought it as a chiller for the k40 CO2 laser. I had a thermometer on opposite side of tank and the heater was dead on true. This has the best controller that I have found on the market. The cover over the heating tubes is great, the turtles claws can't damage the tube. It does blend well in some setups and may look bulky in others. After several weeks of running the heater.

"The FreeSea is amazing."

Very easy to install and the adjustable temperature gauge is pretty accurate. The temperature gauge is fairly accurate in my 55 gallon tank. I like the fact that it comes with a digital thermometer. Thanks for the great customer service! It does blend well in some setups and may look bulky in others. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. So far I like it setup was super easy.

"The seller was wonderful."

The heater is super thin and the reflective surface is interesting. The design is sleek and modern looking. Ick for instance detaches from fish at 86 degrees and dies at 89. This is a powerful heater that holds temperature very well. We wish the controls were available in Farenheit also to make things a little easier. Just be careful and keep an eye on your temp settings when you have kids over! So far I like it setup was super easy.
