good value for money - fish and aquatic animals

We bought this heater and when we went to plug it in we found another heater that didn't kill our fish. We have yet to put this one in the tank, we are still a bit sad about getting new fish.

Pros
  • This is amazing
Cons
  • Expensive insurance

Works good not great

I have this in a 55GW goldfish and I need to set the temp higher than what is advertised to get the temp I want. In this case, it keeps its temperature in order. My Aqueon works better (but also more expensive)

Pros
  • Cool
Cons
  • Updates

Great heater at a good price

I use this heater in a 48 gallon tank. Maintain the temperature without significant fluctuations. I just want to be a real immersion heater. Information on the internet about this heater is scarce. This heater can be submerged in water but no more than 5cm below the water level for better concealment.

Pros
  • Worth the money
Cons
  • Unusable features

a few degrees not calibrated

works and that's all I can say. There were problems with maintaining the temperature and the aquarium was constantly heated. The temperature setting turned out to be over 8 degrees and tested at 79 degrees on the lowest setting. I thought buying a famous brand would pay off, but buying two 100w and 200w models is disabled in the temperature settings. I recommend checking the "calibration" upon receipt and re-checking if you even purchase this product. The "on" indicator is difficult to see and…

Pros
  • looking forward to it
Cons
  • will do

Product received - looks good. I have used many visi-therm products in the past and sooner or later I managed to break them when they were taken out of the water while hot and I forgot and the glass cracked. Anyway, I managed to heat a keg of water that I used to recycle hot water and it didn't even change the temperature of 40 gallons of water more than 5 degrees, even after a night's work. I spent the extra money to buy a more industrial product - the heater can work great in aquarium…

Pros
  • Only positive
Cons
  • Not trendy

Great, but what power to choose - please help!

Great product; After all these years it looks like I've finally found a heater that will keep my large aquarium warm without having to make adjustments every time the temperature changes. Also, it is strong enough to keep the water warm. As for us folks who need a little help, I would give the product ad a one star rating. *** On this page and other pages, you list the different powers that are available, with no help in choosing the power. After spending over an hour researching other websites

Pros
  • Confident
Cons
  • Makes me angry

*Update* I bought this heater in 2016 and it's been a little over 4 years now and it's still working. I can't say for sure the long-term temperature accuracy of this heater just because I paired it with an Ink Bird digital temperature controller (to prevent the tank from overheating in the event of a heater failure) about a year after initial installation. the hydor heater in my tank. But I can say that combined with Ink Bird this heater was excellent and I am very happy with my purchase. I…

  • New to my collection
