      String algae

      I had a string algae break out , So I spread Sodium percarbonate . 3 cups in a 8000 gallon pond . turned off filters . It made some foam on the surface . left overnight . It did not seem to kill it . algae was still green & wavy . So I swept it off with a pool brush, it did seem to come off better . Should I have used more than 3 cups ? should I do it again ? Do I need to neutralize after using it?

      Did you apply it on or close to the algae itself? It usually works best if you do...
      I only have used it once because I didn't like the way it bleached spots on the liner and it made my
      pH skyrocket. I didn't use anything to deactivate it. I don't remember how much I used but here's
      a thread Roddy did on it a long time ago that might help:

      I just use 3% hydrogen peroxide when I get some strings... although I'm having a hard time finding it
      now a days.

      What are we to make of someone asking for free advice, who complains when it's not provided per their expectations? How about searching for and reading threads on the subject, of which there are many here.

      Thanks , I had read the Roddy posts prior to posting . I found the dosage varied -2lbs per 1000g /0.6 lbs per 1000g / 1.5 cups per 4000g.. I sprinkled it all over the string . But now
      a week later after I brushed it up and unclogged my strainers . It seems to be staying at bay.

      I have found that removing it manually works the best for me.

      I use it in my 4200 gallon pond after I uncover it in the Spring. For some reason it grows like heck in the winter. It grows up to 6 feet long and starts to clog my bottom drains.
      I use two cups every other day and after two treatments it's gone.

      I have not used sodium percarbonate. But in those few springs when string Algae gets bad, I'll use salt to up to about 0.15-0.20% to knock the algae back to a managable level.

      My regiment for string algae takes a couple of days and does hurt the string algae. First I brush the walls and bottom of the pond and allow the pre-filters to collect the stuff. The string algae collects a lot of crap and it needs to be stripped off. I PP the pond at 2 ppm and often have to re-dose to keep the color for 4 hours. Next morning I add 1 cup of Hydrogen Peroxide per 1000 gallons. The brown tannish left by the PP disappears within minutes and the string algae is now really suffering. Another brushing and the pre-filter clog up quickly with all the floating algae. I'll do a major water change and add lots of clay with the new water. If I'm having a gathering or party and I want the pond to look great I will use this method 4 days prior to the event.

      I use Gene's Koi Clay every week....It takes care of the string algae and cleans the water up nicely...Also good for the koi.....No harsh chemicals, which I like

      What strength peroxide do you use?

      As best I can figure, as the water muddied by the clay clears, the clay is captured on the surface of the algae. This blocks light and reduces the efficiency of nutrient capture from symbiotic diatom. No studies on point.
