"There was only~0."

No biggie, but annoying nonetheless. My heater is fully submerged underwater and works perfectly fine. The controller is easy to use, very accurate and reliable. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. Easy enough to let it run all the time. I waited a little bit to write the review so it could be accurate. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees.

MarineLand ML90652 Final Thoughts

"I like the size."

Once I opened the box i noticed the quality of the construction. The red light means it's off, blue light means the temperature is constant. My fish likes to get close to it and he has never been hurt by it. My fish likes to get close to it and he has never been hurt by it. They shipped us the upgraded version that also heats! Ick for instance detaches from fish at 86 degrees and dies at 89. Also I like how it shows both the current temperature and the set temperature.

"Works fine."

But I am single and don't have to worry about this. I noticed my old hygger heater beginning to fail and my wife ordered this one. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. Well I bought a second one took me only one trying to get the right temperature. So if you set it to 78 degrees, the heater will not kick on until it reads 76. No biggie, but annoying nonetheless. I went ahead and went with the the larger 300W for my 45 gallon.

"Quality was amazing."

If the water runs low or air gets in the heater shuts off. This heater warmed it right up and now my Betta and guppies are more active. We would consider a replacement and then we would return the defective unit. The temperature has been holding all day, even in a colder room. It is a bonus that the heater is titanium. It just cycles through to 93f and starts over. Seems to keep the temp n the tank fairly regular.

"There was only~0."

It is a bonus that the heater is titanium. No biggie, but annoying nonetheless. I have a 10gallon tank that was at 72 degrees. I had a thermometer on opposite side of tank and the heater was dead on true. The heater protector was very heavy plastic and slim lined which is great. They shipped us the upgraded version that also heats! I like the fact that it comes with a digital thermometer.

"They contacted me."

The suction cups are large, high quality and seem to stick great. It is a bonus that the heater is titanium. Per my thermometers, they are all staying constant. Would be great to be able to tune that to. I left seller feedback yesterday but have yet to hear from the seller. The heater protector was very heavy plastic and slim lined which is great. It does blend well in some setups and may look bulky in others.

"Thank you for reading."

Personally for me the housing doesn't bother me. --The heater itself is a bit shorter if your tank is a short one. Thanks for the great customer service! I got the 200W variant for my 54 gallon corner tank that's housing goldfish. There is a misconception on the internet that the heater isn't fully submersible. I tested it by unplugging and replugging it. Also I like how it shows both the current temperature and the set temperature.

"Will buy again."

I use a 50 for a 5 gal and a 10 gal tank. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. Keeps the temperature within 1 degree of what you set it to at all times. I have a 10gallon tank that was at 72 degrees. I have 3 of the Fluval heaters, in various sizes. I left seller feedback yesterday but have yet to hear from the seller. You program it for temperature you want your tank to be.

"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.

This does a great job at regulating the temp in my 10 gallon. There is no protection from it banging on the glass tank. Pressing and holding the button for 5 seconds changes it from F to C readouts. Temperature is slightly off by running a little warmer. I'm not a big fan of the big glass tubes. I wouldn't buy any other heater, unless one of these stops working. My marina heater takes a few hours.

"No copper lines!"

I will definitely be buying another one for my other tanks at bigger one. The red light means it's off, blue light means the temperature is constant. The suction cups are large, high quality and seem to stick great. The line is there due to regulations in certain countries. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. --The cylinder or rod diameter is bigger. I used to try those other cheap heaters sold on amazon.

So if you set it to 78 degrees, the heater will not kick on until it reads 76. I confirm it with my cooking digital probe thermometer. I recieved this product without the instructions or the added thermometer. The line is there due to regulations in certain countries. This heater warmed it right up and now my Betta and guppies are more active. But my guys don't read them and don't listen! So far I like it setup was super easy.

"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. The heating element is surrounded by a thick plastic to ensure the protection of these caudal-finned betta fish.

"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.
