"Until the next time."

I got the 200W variant for my 54 gallon corner tank that's housing goldfish. I think it works well to not stand out like other heaters. Checked the accuracy of the heater with an infrared thermometer. You don't have to worry about wide temperature swings with this unit. I noticed my old hygger heater beginning to fail and my wife ordered this one. The heater is super thin and the reflective surface is interesting. Two inches above that is a waterline for maximum.

I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. Per my thermometers, they are all staying constant. I'm not a big fan of the big glass tubes.

"Long heater."

For Discus you need warm and accurate heater and this seems to do the trick. Was very impressed with the quality of this heater. Would be great to be able to tune that to. I had a thermometer on opposite side of tank and the heater was dead on true. It just cycles through to 93f and starts over. I went ahead and went with the the larger 300W for my 45 gallon. You don't have to worry about wide temperature swings with this unit.

The temperature lights up so it's very easy to read. The heater is super thin and the reflective surface is interesting. Was very impressed with the quality of this heater.

"I like this heater."

Now, both points are clear on the package instructions. We received the chiller promptly and put it into use. Well I bought a second one took me only one trying to get the right temperature. The cover over the heating tubes is great, the turtles claws can't damage the tube. I use a 50 for a 5 gal and a 10 gal tank. My marina heater takes a few hours. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank.
