My 54x54 pond is handling the trout fine as of now, the trout weight about 4-6oz now x 600 trout, the ammonia is staying at 0 and on warm days the temps creep up to 68 degrees. Water temp is mainly around 64, I run about 4k gallons of well water a day to help with evaporation. ph is also staying at 7.8-8.0. The fish seem very active and healthy
