For example, my bloom starts in early June when the lawn fert goes down. We don't intentionally put it in the pond but some runoff gets there. It usually is pretty consistent during hot weather but for some reason when weather cools the bloom stops. Last week I for no reason noticed the water 'clearing' up and the bloom weakening. Every day it was noticeably clearer. I tend to get revival of FA in the shallows this time of year as well so I think the nutrient balance, FA and temps have to do with it. Of course the fertilizer effect only lasts for so long too so that will peter out the bloom too.
