Hydor 75w Hydrokable Substrate Heater, 25' - for Aquariums 32-53 gal

This heater does at it is supposed to--heat via substrate. My big complaint is that it did not come with nearly enough suction cup attachments. I have a 55G tank and looping/winding the cable the way you're supposed to only half the tank was secured. It was basically impossible to find other suction cups for it. I had to order them from the company at a pretty ridiculous price--and even then predictably some of them didn't hold well. Fortunately they really only had to hold a couple minutes until I could get the sand/clay over it and then the weight of the substrate holds it down.

46 bow...with an internal heater working with it...78 is max temp. It is not adequate without assistance. If you want this as your main heater...try something else!

Using this in my planted 55 Gallon aquarium. Works perfect! Only issue I wish they included more suction cup fastners.
