Just would like to add what I have been trying for my 2yr old pond. Pond is approx. heavy 1/2 acrer.Yard run-off and house and garage have down spouts trenched to pond. This spring tried southern excellent fertilizerand with-in 3 days filmentous algea every where. Put in cutrine plus and aqua-shade,only lasted about a week and it was coming back. More cutrine and aqua-shade and back again in week. Found a amish family that grows barley straw (mixes the barley in with feed for their dairy cattle)and sells it for 1.50 bale. I drove down to jasonville, Indiana where they live and bought 20 bales, got home put about 10 bales around pond banks in 1 foot water, and with-in 3 days hardly any filmentous algea at all and has turned water a nice shade of green. I am very happy with the results after just 1 week. I should mention pond is approx 10 ft deepest, and i have a 1/4 hp gast ariation system with 2 duffusers. Just hope this helps someone at there.
