I agree to discontinue using it. I'm not sure what kind of turtle you have, so I don't know how warm you need it. . . But I think its usually between 2.5 WPG and 5 WPG for most things. So, if you want one of the same 400 Watt heaters you have right now I would suggest sticking with the same brand. I've never had much of a problem with Hydor and you can get a cage to go around it to protect it from the turtles.
