Mike, I have been reading your soldier fly thread with great interest. Whenever I read your posts, I am impressed by the methods you use to naturally control environmental conditions. SFL is something I am looking into, thanks to you.
"Nutrient Pollution" is mostly impacted by the watershed, feed and total fish. If you feed fish, algae blooms are the price you pay. A percentile of high protein feed ultimately ends up becoming nutrient pollution in the sediment layer, primarily from uneaten food and secondly, fish excrement. Eventually, the bottom becomes anoxic due to TAN buildup.
