Hello everyone. I have a 12 x 30 index pool I'm using temporarily until my pond is done. Unfortunately due to a surgury I must wait to finish after winter. I live in southern Louisiana and need to know if I can keep myintex pool up and running through winter. I have 5 koi and 10 watonai with the largest of the group being about 9 inches. I had the watonai last winter in a 300 gal trough and with no problems. The winters here can have a day or two with temps below freezing but rising back to the low 40's. Would I need to insulate the pool someway or would it be ok as is? I would cover it with 6mm plastic. Any suggestings greatly appreciated.
