"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.

"No issues."

It took me a few days slowly turning the dial up to finally get it where I wanted. The bonus digital thermometer it came with has been super helpful, and is accurate. The line is there due to regulations in certain countries. I have it set to 81F to get a 77F water temp. The cover over the heating tubes is great, the turtles claws can't damage the tube. The temperatures are pretty accurate. I dont know, and havent tried just yet.

"5 gallon tank."

I went ahead and went with the the larger 300W for my 45 gallon. The heater is super thin and the reflective surface is interesting. The bonus digital thermometer it came with has been super helpful, and is accurate. We wish the controls were available in Farenheit also to make things a little easier. Bought it as a chiller for the k40 CO2 laser. Pressing and holding the button for 5 seconds changes it from F to C readouts. Beware, but we are hoping for a good outcome!

  • SunGrow Betta Plakat Heater, 10-Watt Submersible Aquarium Water Heater for Small Tanks (1.5-Gallons), with Preset Temperature Capability, Suction Cups Included
  • ✔ KEEP YOUR BETTA HEALTHY --- To ensure that your betta has optimal health, you need to provide her with warm water. The water in the tank should not go below 74°F for optimal comfort and metabolic efficiency of your crown tail betta. The cold temperature for this gourami family fish will make her lethargic, stressed, and miserable.
  • ✔ AUTOMATICALLY REACHES THE PRESET TEMPERATURE --- The smart SunGrow heater for this freshwater fish has a built-in electronic thermostat to automatically maintain water around 72°F which is ideal for most tropical fish. It saves you from the trouble of constantly keeping a check on the temperature of your tank. It will automatically shut down when it will reach the desired temperature, no manual adjustment is needed.
  • ✔ CREATES THE IDEAL CONDITIONS FOR FLORA AND FAUNA --- The eastern Asian fish species can survive in a freshwater environment. This heater by SunGrow will create ideal conditions for them. A few preconditions are required to allow it to run with maximum efficiency. The heater must be completely submerged in the water and the indoor temperature should be around 62-74°F.
  • ✔ SUCTION CUPS INCLUDED FOR EASY INSTALLATION ---- Easily install the SunGrow Heater vertically or horizontally by using the built-in suction cups to attach to your tank. The best location to place the heater is in the stream of a powerhead or near the water flow, such as the outlet (or inlet) from the filter. This way the heat is evenly distributed throughout your tank.
  • ✔ FULLY SUBMERSIBLE WATER HEATER--- This 10-watt aquarium heater supports 1.5 gallons (5 liters) fish tank. Its exterior is designed with tougher than glass and the sealed polymer can be submerged into your tank.

"Temperature!"

It would stick out of my 30 g wide tank if I were to put it vertical. It took about an hour to reach 80f, which is fairly quick. My fish likes to get close to it and he has never been hurt by it. Was very impressed with the quality of this heater. I left seller feedback yesterday but have yet to hear from the seller. I will be ordering more of these in the future. We received the chiller promptly and put it into use.
