Hi, I found a bucket of silica sand in my garage. I was wondering, is all silica sand ok to use for cp's? Or do some of them have Additives? I washed it with pond water then used bottled water for the final rinse. Is it ok to use?

You can wash it first, then use a TDS meter to test it before and after mixing boiling water with it. Also you can use vinegar to test the sand after that. Willy
