Hello - quick question. Long story short but my pool guy installed the ichlor 30 instead of the intellichlor 40 like I originally asked. Anyway - after much discussion he finally agreed to install the intellichlor 40. In any case, with the ichlor, through the app, I could set the % in increaments of 1%. My understanding is that with intellichlor - it is in increments of 20%. However, I notice that in the app it still adjusts by 1% increments. I am wondering if I in fact can do the 1% increment or if I need to just set the app to 20% increments (i.e. 60%, 80%, 100%)….Thanks!
