A: Hi on starting up you need two tablets . Then on a weekly basis you need one . It can take about ten days for two to dissolve and then one usually takes a week . When we first used it it was a little foamy that goes away after a week . We have had know problems with only one tablet a week the water is crystal and doesn't smell to strong . We also change filter once a week same day as new tablet . Hope this helps . We use it every day .
