OxiClean as algaecide

Have any of the members tried using OxiClean as an algaecide? The MSDS shows OxiClean is mainly 50-70% Sodium Percarbonate. Here's a description of Sodium Percarbonate.

Sodium percarbonate (Synonyms: sodium carbonate peroxyhydrate, sodium carbonate peroxide, PCS) is a free-flowing powder with a common name of solid hydrogen peroxide, it is an addition compound of sodium carbonate and hydrogen peroxide. Percarbonate has an active available oxygen content which is equivalent to 27.5% H2O2. It breaks down to oxygen, water and sodium carbonate upon decomposition. It's an environmentally safe bleaching agent.

This is a good question. Why don't you call/email the Oxyclean people and ask? Then post the response here. Be sure to tell them that most growers use their systems to produce food crops.

RE: OxiClean as algaecide

Aside from trying to determine if OxiClean is a potential source of hydrogen peroxide for algae control I tried to figure out if it would make sense cost wise. I'm assuming 1 Tbsp. of OxiClean is equal to 1 oz. I'm also assuming a 300 PPM solution. Based on these assumptions it is seven times cheaper per gallon to use the OxiClean than the 16 oz. bottle of 3% Hydrogen Peroxide.

Item--------OxiClean Reg. Formula---3% Hydrogen Peroxide
Wt. Lb.-----3.5------------------------1.0
% Sol.------28%------------------------3%

By the way got a nice email from the Orange Glo Corp. in response to my query asking me to call during business hours and talk to a customer care specialist.

Check outn this EPA registration for a product for horticultural uses containing the same primary ingredient. An important question is what are the inert ingredients?

Here is a link that might be useful: Terracyte

RE: OxiClean as algaecide

Good find and good question. No mention of any trace elements in the EPA document. In the mean time I'm using a 1000 PPM solution of OxiClean to clean out my buckets.
