Dichlor has stabilizer in it commonly called CYA (cyanuric acid) it is in there because dichlor is mostly used in outdoor uncovered pools subjected to sunlight. Sunlight breaks chlorine down fast and CYA slows the action. In a uncovered pool the CYA needs replaced as you add more chlorine so they combine the two in dichlor. Hot tubs are covered most of the time so the CYA/stabilizer builds in the water. A little is good a lot is bad. About 30-50PPM is good as it lets the chlorine act slower over a longer time.

I use dichlor until I hit 50PPM and then I switch to liquid household bleach Clorox or the cheaper Walmart brand. It is chlorine without the CYA. You cant seem to be able to buy a granular chlorine without the CYA added or I would switch to that. I use the Clorox until I see the CYA drop to 30PPM then I switch back to dichlor for a week or so. It drops because you splash water out and add fresh here and there plus some just goes away.

Keeping that level just right IMO helps the tub remain stable thus why they call it stabilizer.   ;)
