I converted about 3 weeks ago, the best thing I've ever done. You will go through lots of bleach and lots of different colors in the pool. Just keep the bleach levels up, clean the filter and you will soon have the clearest water you've ever had. I didn't worry about any other levels in my pool until I got my water cleared up. Once it would hold chlorine overnight and I changed my filter, then I balanced my water!
Good Luck!!
