Interesting information on algae killing chems
Permalink  
 


I came across this patent and thought it had some pretty interesting information about killing algae. It is kind of technical, but has great information.

http://www.patentstorm.us/patents/6291397/description.html

They talk about using sodium dichloro-s-triazinetrione, which is granular chlorine, along with a bunch of other dry chemicals and disolving them in water before the application. It gives you a solid form of "chlorine" that has a super long shelf life.

I know Chris Tucker has experimented with all the different powders with little success, but this patent shows there is a way to do it.

I Gotta do a lot more research confuse

Intresting, that kinda blows my "this is why other stuff dosn't work" post earlier away perhaps?? Maybe one day this will work?? I would love to see it happen, then I could order 1 ingredient instead of 5.

Yeah I believe it's the same stuff used in my chlorinating tablets (Have to check). Interesting read.

     I get my SH from a local pool store, which happens to be owned by a good friend of mine. He has allowed me to test certain chems to see what the results would be. the powder, specifically powdered chlorine, is fine for use on housewashes and gutters, etc. BUT, it did not work for roofs. It seems to me that the concentration of water/SH may not contain a pH high enough to kill the algae on roofs.

The calcium hypo isn't a good substitute for liquid hypo in house washes. It will work, but it will leave a white residue on anything it touches,..plants, wood decks etc.... It is nice only for the fact that it can be stored and mixed on site, but it never dissolves completely and the mess it can potentially leave isn't worth the trade-off.
Stick with the liquid.

Good point Jeff. And I meant to mention that in my original reply. There was definitely extra rinsing required when i used the powder, enough so that I wouldn't use it again.
