Pvc or preformed pond liner
I am in need of a heater for my approximately 100 gallon outdoor fish pond. We have three fish - two gold, one koi - and the pond is hand dug with a pvc liner (rather than the pre-formed type liner). The last pond heater we owned looked similar to a floating pond deicerl, but I am unsure about wattage, etc. I need something that is economical, but will help my fish survive the winter in West Virginia. Thank you for any advice!
