There really is a ton of misinformation out there on the internet.

People have all of these preconceived notions about what is safe or biodegradable after reading all of these roof cleaning chemical companies web sites.

I spend more time trying to educate my customers about the proper roof cleaning procedures and chemicals than I do anything else.

For anyone that hasn't checked out AC's Orlando roof cleaning web site, you should take a look. The history of his company is pretty interesting.

ALl of it is Biodegradable. In fact most things are. TSP..... ok we will try this again.....

Phophates cause algae to grow!!!! Particularlly Brown Algae. This form of algae grows so thick that it block sunlight in water and kills the fish!! That is why phosphates can be considered an enviromentall danger. Most people do not realize that enviromentall dangers don't always have to kill something, they just have to change the enviroment in question to a potentially dangerous enviroment for some of the creatures living in it. In fact for most people if a product they can buy says green, they will buy it and feel great!! Unfortunettly the best thing for consumers to do is NOT BUY PACKAGED THINGS AT ALL........

Algae is not a technical term and neither is bleach.\
Bleach is: anyhting that lightens or removes color
Algae is: primitive chlorophyll-containing mainly aquatic eukaryotic organisms lacking true stems and roots and leaves

SO ...the algae we are combating is from the phylum: cynabacteria.....it is similar to mold in that it has airborn spores, it is similar to other algae in that it is like algae in every other way. Most algae do not have airborne spores. It is one of the simplist forms of life on the planet and is beleived to be over 2 billion years old!! It produces oxygen as a waste and absorbs water carbon and calcium for food.

SOOO... To ACTUALLY ANSWER YOUR QUESTION. There is no great argument for it, you are using very little and that is a good thing, most people are dumping tons of phosphates into the ground water DAILY when they wash their car or do their dishes. and your right they are not particularly dangerous except for algae bloom and ingestion. The simplest way to deal with it if it is a problem in your area is don't use it!! It helps clean faster and stronger, but is not neccesary.

Generally people are going to ask about the SH, not the other ingredients.

The term Green is the worst part about all of it, seeing as phosphates cause a plant to grow!!!
No wonder consumers are confused. How do we continue to consume and not do harm?? Well unfortunettly nature has not solved that dilema, life feeds on life and all life harms as well as helps other life....Its called life, lol...nature seems both cruel and loving to those who understand what is really going on here. The best thing any human can do for our planet is stop making more humans and stop buying products they do not need. Building the house in the first place has done more harm to the enviroment it is sitting on, than anything else. Maybe people think pink flowers and bunnies live in their walls because their drywall said green?? I don't know, but I do know that you can't argue with some of them. And if they already sprayed pesticides all over their yard then.....WTH are they talking about in the first place, they have poison all over their yard already.
