Vibrant Life 50 W Aquarium Heater

The suction cups/clamps that come with it to hold it in place are SUPER flimsy, so I'd recommend purchasing replacements or just different suction cups to begin with. I went to change a percentage of my filter water and it was barely removed from the surface of the water and melted the clamp so absolutely make sure it's unplugged without a doubt during any water changes, even if you think it'll remain covered in water. It definitely keeps my tank warm for tropical freshwater fish! Just needs stronger and more durable clamps to hold it in place. :)

Great heater you can manually adjust to the temperature you need. This is our Second one because the first one works so great in the other tank. Highly recommend this one over the automatic temperature ones

The instructions are a little confusing. I can't tell if it works all the way or not. Like there's a temperature indicator that has two readings- a dark red one and a light red one. The light red one is the one that you use to show what temperature you are setting the heater at. I cannot figure out what the dark red temperature indicator is for. You'd think it would be to indicate the existing temperature, but when I used a separate, trusted aquarium thermometer, it showed a different temperature. Unclear if the dark red indicator is for scale or what, so I am not sure how to rate this. Other than that, it DOES heat the tank. You would not know it because, depending on the dark red indicator thing, you might have to trust it blindly or use a separate thermometer. But it does heat the tank to the desired degree.

This aquarium heater does a perfect job keeping the tank at a steady temperature

perfect for my 5 gallon tank.

it doesn't heat as much as I needed

I have a nice 10 gallon aquarium with a few ‘mystery snails', in it. And they need to thrive in a certain temperature range. This heater is excellent, it keeps the water temperature within the desired range that's needed. It's very easy to use, and very safe to keep your water pet's happy and healthy.

work out perfect

Has a very good taste to it.

easy to use, well made heater for smaller aquariums. used it in one of my ten gallon tanks and it works very well.
