Great site! I have a 1 acre pond with a depth of ten ft sloping to 4 ft. There are four springs feeding this pond. I measured the outflow of water and it is roughly pouring in at 1,000 gallons an hour.(The pond was completely full in 35 days!!!)With this much inflow of fresh water can you advise on the need for aeration?? The pond was dug in August of this year.
