:-) Allright then, my bad for not being clear. I meant 'pure' as in what vendor carries a granule based chlorine pool product that has the least amount of other chemical products in it (calcium, stabilizers, etc). In my case, I have to store the liquid bleach in the garage, and I either have to carry it through the house (most direct route) or take it outside and around the house (more convoluted route). I was not as concerned having to carry granules through the house as if I were to spill them, I could vacuum/sweep them up. Liquid bleach would be a disaster. I can't store the bleach near the pool.
