I have a 1/4 acre pond with a max depth of about 10'. Most of the spring and summer I have water running out the over flow. I have been aerating the pond for the last two years with a easy pro linear pump. I talked to a pond biologist that said I would have a much clearer and healthier pond with a bigger aerator. He suggested a Gast rotary vein aerator. Do you think this would be an over kill?
