Pond Boss Forums MANAGING AN EXISTING POND Fertilization Fertilization with aeration

Anyone else have a problem getting a good bloom with aerated pond? Since I started aerating it seems like my fertilization requirement has increased three fold. Is this the norm or is it unusual?

Since aeration stirs the pond, perhaps fertilizer which was previously concentrated in the plankton zone is now mixed better and hence less concentrated? Could your normal fertilizer application method have been placing it predominantly in the upper water?

It may not be a fertility problem but a water turnover problem.

I assume that your fert. program worked before and no change in the water condition (alka. etc) has occurred. In other words the only change from when it worked to now is the aeration.

If so a possibility may be -- if pond is turning over at a high rate due to aeration you may be sending the plankton to the bottom (out of the sunlight) to much to keep a good bloom. It can die (individual warmwater plankton) when it is subjected to no light and cold anaerobic conditions at the bottom.

Could it be possible that aeration causes the existing bacteria to decompose the natural fertility that had existed before? Just throwing out a thought.
