Ewest, tell me about it. In the heat we've been having I've seen it double every day. I usually have to do this only 3 or 4 times a year and I think I've done it 5 times already. Here's an interesting note. This past spring I began pumping my pond water out into the bog in hopes of filtering nutrients out so that I wouldn't get so much of this stuff. Impossible to tell if it worked at all cause I think the weather plays a large part. But while I do have a bumper crop of DW this year I have almost no FA. Does the heat inhibit FA or could my removal of nutrients helped? I think the only way I'll ever know is to do some nutrient testing periodically for several years. Anyone know of an inexpensive way to do that?
