i am new to this board, and what i have been reading here the last couple of weeks, this is awesome. a lot of good info here. here is my problem and i hope someone can help. i have a .85 acre pond about 2 1/2 yrs old 5 1/2 feet deep. i have been battling algae this year and it is driving me crazy. i have the floating algae and what i think is chara. the algae is so thick that it is clinging to the chara and looks like it is coated with mud (1/2 th 3/4" thick on the chara) i have been treating it with crystal plex at the recomended dosage. i was told by the distributor that i should treat 1/3 at a time. i am on my last treatment and then they told me to use bio clear after the last treatment. i will do the last treatment tomorrow, but i wanted to rake out as much as i could first. i also read on other posts that a pool skimmer would work well for getting as much of the floating stuff out before treatment. got any ideas on what will work best for killing the algae, as the crystal plex does not appear to be working. i am thinking about cutrine + does the liquid or the granular work best. by the way, the pond has lb and bg in it.
