So..Information is your friend..
I could not find the SDS on their
website but a simple google search turned up this:
and that says it has 35-50% Copper Sulfate, 30-45% water plus other stuff. The chelating agent is proprietary, so who know what that is. One of the philosophies of this site is to know what you are putting in your pool. And they don't want to tell you. The FAQ on the website is instructional
-"7. Can I test for the PoolRx minerals in the water?-No. The minerals are uniquely chelated. This is one of the things that sets us apart from other copper-based products."... In other words, We don't want you to know what you are putting in your pool, except for the copper.
-"8. Can I use other copper-based products, with PoolRx? No, Do not use other copper based products with PoolRx. (You won’t need to, but more importantly, you don’t want to saturate the water)"...Oh, I can't put somebody else's copper in my pool, I can only put YOUR copper in my pool. Got it. And in some round about way they say too much copper is bad, I guess.
-"PoolRX contains a proprietary blend of minerals that continuously and effectively eliminate algae " That doesn't tell me what it is. I have a proprietary blend of minerals in my back yard, its called dirt.
-"16. What type of chlorine can I use? All types of chlorine are compatible with PoolRx " -I think they mean "chlorine products"... because chlorine is chlorine. All day long we tell people that an SWG puts the same kind of chlorine in your water as a liquid chlorine. The method of delivery is different. And with that method of delivery are by-products that you should know about. But that statement just made me wrinkle my "knows".
So
@bkbaird we are all about education.. if there is a better way, we are all ears. And trust us, that "way" will get dissected and analyzed here.
