I remember someone talking about Clorox outdoor a month ago or so. It comes in a gallon and a half container, and I bought some at Home Depot. What I'm not sure about is how much of it to use in a 5 gallon mix. It appears to be a concentrated product, packaging says it makes 30 gallons. Just wondering if anyone out there is using it, and if so, how much per 5 gallons. I believe this is stronger then the "Ultra Clorox".
