R. Wicker :

Not sure I understand your answer. I will ask the question in a different way.

Many (a high % of) ponds in the Southern US and parts of Texas are naturally infertile and acidic with low buffering ability. Alkalinities are form 4 to 20 ppm ( very low buffering ability) and thus many people use ag lime and high P fertilizers to increase fertility and thus carrying capacity. These ponds , most without aeration, have a summer thermocline and anaerobic pond bottoms in summer and more bottom O2 after fall turnover.

What would the product do in those conditions wrt alkalinity and P fertilization ?
