Pond Boss Forums INTRO Questions & Observations floating algae

i have a 1 1/2 acre pond dug from 18" to 12' that recieves more run off than it can handle, spreading out , also recieves much more nutrients , i plan to aerate, money only hold up there, last year kelly duffie helped me remove coontail,and with cutrine plus control the algae, this year with more rain than usual for central tex. i have not been able to apply , just washes out spill way pipe. scum type algae is now formed into the pad that floats, now i can probably add cutrine at 1/15 , 2 gallons, which will kill algae, here is where i have a question. as algae decays, it will create more nutrients, should i :
add bacteria and enzymes after i cutrine plus ?
i also remove as much as physically possible with a pond rake, thanks for comments, i read this everyday and subscribe to the mag. david 903

David--

Try spraying the Cutrine directly on the floating mats that you con't manually remove--it will croak almost instantly. Focus on aeration is so important, of course. Physical removal of the algae is a great idea, especially without aeration, and if you decide to add microbes just wait until the algae has been killed back because the bugs don't eat it when its alive.

David,
Floating algae mats are almost always already dead. Look for different shades of green/yellow/brown colors in the mat. Algae grows quickly, dies quickly, begins its decomposition process and floats into large mats, moving with wind and waves. Treating with algaecides won't help the mats. As a matter of fact, treating with algaecides makes bigger mats, because you kill living algae, which dies, then floats. Microbes assist in the rapid degradation of algal mats. Or, you can rake it out.

Bob, that's interesting to learn; almost all of the filamentous algae in our pond floats in mats, uniformly green (thank heavens there are ever fewer of them); when I hit it with Cutrine it turns brown within a few minutes/hours, but doesn't always break up until I disturb it manually. What am I missing in terms of understanding its life cycle? (By the way--I think you ought to exercise adminstrative privilege and knock me down a couple of stars on the rating system--I'm sure learning what I don't know!!)

thanks to both of the replys, always helps me to get someone's else opinion advice, course we have gotten more rain 8.65 inches this month! will try rake out , and then treat with aquaace, aqua/duece, suggested by kelly duffie. david 903
