Hydor 200W Submersible Aquarium Heater - Original Theo

This heater works great I have it set just a little bit higher than it's lowest setting and it is working great. I have it in about 50 gallons of water and it handles that with no problem...

This heater has exceeded my expectations. Although, I expected this heater to be a little be longer being that its a 200 watt compared other other brands it was very strong and kept my 80 gallon tank heater and it was percise.

On the box it says that the 200 watt heater is for tanks up to 56 gallons. I find that it is good enough for a 80 gallon.

I bought this on 1/19/2010 and then set the temperature to 77. It kept the water temperature to 82-83. It worked for the winter. When summer came, I unplugged the heater (still keeping the unit in the sump). Then with fall setting and as temperature started to fall, I restarted it. Overnight, the tank temperature shot to 92F and I saw all fishes gasping. Needless to say, lost my flame angel, mandarin, Clowns and Fire fish. That was one big disaster.

I called Hydor up and the gentleman said to send the heater to them as they wanted to check for abuse. He was very polite and seemed logical. He also mentioned to send in the least expensive way so I put it in an envelop and sent it. Four weeks passed and I did not hear back so called them. They did not receive it and unless I could show proof, would not send me a replacement. I guess in todays world, that is how it is...

If you buy this product, make sure you have temperature alerts to warn about overheating and if you have issues with the product and want to send it back, make sure you keep proof of delivery.

I ordered this for my turtle tank, after deciding that my local pet store was way to expensive. I have a 50 gallon tank that is over half full I plugged this in and within a few hours it was up to temperature and has stayed there. I was looking at heaters specific for turtles being concerned he may shock himself, because turtles like to climb on everything in their tank. This heater is shock resistant so its perfectly safe. My turtle lays on this and is fine. Also it is completely submersible and can lay flat or upright. It is just awesome and in the pet store they want over $50 for one like this.

My heater, when turned all the way down, kicks on around 79-80 degrees. It needs to go lower obviously. I plan to put it on a separate controller since the reliability is so weak. I'd advise you do the same if you purchase this.
