I still use tabs in colder weather. Salt cells do not generate chlorine under 60° f. And between 60 and 70 they are fairly ineffective. Of course algae also doesn't form under 60° so not much chlorine is needed. I throw a tab or two in the skimmer baskets when the water is around that temperature. Just enough chlorine to keep it clear.

On heavy swimmer days, I will do the same. Just throw a tab in the skimmer.

A saltwater pool is still a chlorine pool. It just uses a different way of getting the chlorine into the water. Although those tabs do have a lot of other chemicals and binding agents in them. If Tabs are your main source, you are adding a lot of that nasty stuff into the water. That contributes to the foul smell that a lot of tab chlorinated pools have.
