Good evening everyone
Our local zoo is looking to update their otter pool. Right now, they recirculate the water with one suction pipe and one return. It's all 2" pipe and they use a 1.5 HP super pump and a pair of 24" sand filters. There is no sanitizer in the pool. They keep it clear by wasting a LOT of water and refilling with fresh water. The water bill has gotten high enough that they want to redo the pool properly. After some research, our initial plan is to install a commercial ozonator, a chlorine feed system with ORP control and a pump capable of 1.5 hour turnovers. We also want to install a surface skimmer, floor returns and floor drains. If anyone has any experience with otter or other animal pools, let me know. Thanks

Brad
