VIVOSUN Final Thoughts

"I bought the 7."

It is a bonus that the heater is titanium. I use a 50 for a 5 gal and a 10 gal tank. Sometimes it gets outside of it's ability to cool but only within a few degrees. I contacted the manufacturer and they sent me a new unit in less than a week! But my guys don't read them and don't listen! It took about an hour to reach 80f, which is fairly quick. I used to try those other cheap heaters sold on amazon.

"So far so good."

This is a great heater that is very easy to set up and program. 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. I dont know, and havent tried just yet. I'm not a big fan of the big glass tubes. And I get to keep the first one I bought! I got this heater for my 55 gallon aquarium.

I use a 50 for a 5 gal and a 10 gal tank. I used to try those other cheap heaters sold on amazon. I will be ordering more of these in the future.

FREESEA Final Thoughts

"Highly recommended."

So when I first received it it didn't work and I was very disappointed. The temperature gauge is fairly accurate in my 55 gallon tank. I will definitely be buying another one for my other tanks at bigger one. I have it set to 81F to get a 77F water temp. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. The heater is being used in a 40 gallon breeder. The bonus digital thermometer it came with has been super helpful, and is accurate.

"Until the next time."

Come on Fluval, expect better from you. We wish the controls were available in Farenheit also to make things a little easier. Easy to read the temp and know exactly how warm the water is. There is no protection from it banging on the glass tank. I was worried about the quality but I am thoroughly impressed with this heater! The temperature has been holding all day, even in a colder room. This is a powerful heater that holds temperature very well.

"No worries, though."

The bonus digital thermometer it came with has been super helpful, and is accurate. You program it for temperature you want your tank to be. Well I bought a second one took me only one trying to get the right temperature. Sometimes you may have to tinker around with the dial. The heater protector was very heavy plastic and slim lined which is great. So if you set it to 78 degrees, the heater will not kick on until it reads 76. I left seller feedback yesterday but have yet to hear from the seller.

I use a 50 for a 5 gal and a 10 gal tank. It would stick out of my 30 g wide tank if I were to put it vertical. I use a 50 for a 5 gal and a 10 gal tank. It is a bonus that the heater is titanium. --Temperature adjustment labeling is on top rather than on the rod. But I am single and don't have to worry about this.

"Great heater."

It took me only two tries to get it to the correct temperature. It does blend well in some setups and may look bulky in others. The red light means it's off, blue light means the temperature is constant. We would consider a replacement and then we would return the defective unit. This is only day one though, so I shall keep an eye one it. Well worth the money the first one I bought still works great. So far I like it setup was super easy.

"The seller was wonderful."

So when I first received it it didn't work and I was very disappointed. Was very impressed with the quality of this heater. The red light means it's off, blue light means the temperature is constant. Temperature is slightly off by running a little warmer. I have 3 of the Fluval heaters, in various sizes. I wouldn't buy any other heater, unless one of these stops working. For Discus you need warm and accurate heater and this seems to do the trick.

  • Eheim Thermocontrol e100 Heater
  • With the EHEIM thermocontrol-e heating element your fish get the right temperature even more precisely - in every aquarium. The EHEIM thermocontrol aquarium control heater is a further development of the legendary heating element and thermocontrol-e is the latest electronically controlled variant. The obvious ideas are often the best. This also applies to the aquarium heating element. It is simply hung in the water and heats it up. The principle is the same as it was decades ago. But in the meantime the EHEIM controller heater has become an ultra-modern thermal device. The temperature can be set precisely from 68°F to 89°F. It is measured even more precisely and kept more constant by the electronics with a control accuracy of 0. 5 °C. The heat is kept constant with an LED that indicates the heating function. The coating on the heater is made of special laboratory glass that increases the heating surface, serves as a heat shield and ensures even heat emission. There are no cracks and hairline cracks through which condensation water could pass. It is impact resistant. And even extreme temperature fluctuations, such as those that may occur during water changes, do not affect this glass. The heater is absolutely waterproof, can be fully immersed, has a dry run protection (Thermo Safety Control) and is suitable for fresh and marine water.

"The FreeSea is amazing."

I confirm it with my cooking digital probe thermometer. Just be careful and keep an eye on your temp settings when you have kids over! It took me only two tries to get it to the correct temperature. This has been in my fish tank for a few months now and it's been absolutely perfect! Very easy to install and the adjustable temperature gauge is pretty accurate. I think it works well to not stand out like other heaters. I got a hold of Amazon, who put me in touch with the seller.

"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.

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.

This has the best controller that I have found on the market. The temperature lights up so it's very easy to read. I have a 10gallon tank that was at 72 degrees. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. Checked the accuracy of the heater with an infrared thermometer. Now, both points are clear on the package instructions. This little heater is perfect; this is our third purchase of the same heater.
