Ewest, well, both. I understand that ultimately I need to get rid of the algae and that would cure my problem with the fuzzy rocks. I've been spraying the algae when it forms... should I be treating before it forms? I suppose it would take the same amount of chemicals either way so I guess I'm answering one question for myself. The other question is now that I already have the fuzzy rock problem (due to the dead FA), is there anything I can do, without too much labor, to get rid of the dead stuff. Will aeration really help break it down faster? My hangup on installing some sort of aerator is that it couldn't be used all the time due to my geothermal loop but I am willing to sacrifice some occasional inefficiency to clean up the bottom of the pond if it would work. Keep in mind the area I have a problem with is in the first 3-4' of depth along the edges of the pond.
