Hydor 50w Hydrokable Substrate Heater, 20' - for Aquariums 16-33 gal

UPDATE:

The cable just stopped heating a few weeks ago. If they sent me a free replacement, I wouldn't take it, because it's not worth enough to pay me for the 10 or so hours it would take to lift 30 lbs of sand and all the landscaping out of my tank to replace this thing. *Sad*

OLD REVIEW:

The cable is heating my tank nicely, under a sand bed. I'm using it with a thermostat.

The installation was a bit alarming, because the suction cups only stayed on for 5 minutes at first. Then I reset them 3-5 times, and they stayed on long enough to cover the cable with the sand. I'm pretty sure they're stuck in place just fine under the sand, but I would not use them without substrate or with easily movable one.

Not sure if it's absolutely necessary, and a lot more expensive than the typical heater, but with the Hydor thermostat it works great !!

Product appears to work well, but I purchased it for a little 6 gallon tank that will be housing small jellyfish. When I received the cable I placed it into the tank and tested it out before I let it with my fish. The cable was much longer than what I personally needed for the small tank, and so there was much still outside of the tank. After about an hour the entire cable was extremely hot. Hot enough to not be able to touch, so I unplugged it, waited for it to cool, and took it out of the tank.

It may be a good cable for tanks in which you can place the entire cable in, but if you are looking for something to hide in a small tank like I was, not sure it is the product to use if you can't place the entire cable in it.
