Hey all! I've been looking at trough heaters, and I'm really not sure what to get. My trough is going to be somewhere between 50-100 gallons, plastic, and the electricity in the barn isn't horribly strong, I don't think. So far, most of the tank heaters are 1000watts or more. I've seen some pond de-icers at 100watts, but I'm not sure how effective they'll be in a tank. Also, since I will only be out about once a week, I really can't have that trough freezing up, so the heater needs to do a decent job.
Any product suggestions?
Thanks!
