Problem with dichlor use all the time is ur cya will go very high and make sanitizer not ineffective. Not good. Mps has been know also to have sensitivity. Since I have been using my bleach only, no more smell and it works perfect. I just leave the cover off for about an hour after I shock. Also it makes your combined chlorine really low, so not much bather waste after shocking . Trust me I was using the dichlor solo and I had problems with cya, smell and longevity of water between fills. Also bleach at Walmart is soo soo cheap to sanitize just don't use splash less . Just Clorox regular 6%
