"One word of caution."

The temperature gauge is fairly accurate in my 55 gallon tank. 210 gallon ones and one 90 gallon bow front tank. I got the 200W variant for my 54 gallon corner tank that's housing goldfish. I had a thermometer on opposite side of tank and the heater was dead on true. This is a powerful heater that holds temperature very well. Keeps the water consistent and it's easy to adjust! I confirm it with my cooking digital probe thermometer.

"I'll try once more."

The heater is easy; turn the dial to set temp and plug in. We wish the controls were available in Farenheit also to make things a little easier. I was worried about the quality but I am thoroughly impressed with this heater! I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. When i installed them, i let them sit in the tanks without power for 6-24 hours. This is a great heater that is very easy to set up and program. Would be great to be able to tune that to.

"Excellent build quality."

Come on Fluval, expect better from you. I have only had minor problems with the suction cups. The bonus digital thermometer it came with has been super helpful, and is accurate. This is a great heater that is very easy to set up and program. All seem to vary between 1-2 degrees of each other which doesn't concern me much. But my guys don't read them and don't listen! Two inches above that is a waterline for maximum.

"I bought the 7."

The red light means it's off, blue light means the temperature is constant. --The cylinder or rod diameter is bigger. I think it works well to not stand out like other heaters. This heater is NOT fully submersible. This this is amazing and is worth the money. Sometimes you may have to tinker around with the dial. For Discus you need warm and accurate heater and this seems to do the trick.

"This heater works great."

This does a great job at regulating the temp in my 10 gallon. I adjusted the set temperature a little lower to be more in the range I wanted. --The heater itself is a bit shorter if your tank is a short one. No biggie, but annoying nonetheless. The setting always stayed the same. This is a great heater that is very easy to set up and program. There is no protection from it banging on the glass tank.
