Anyone using water softened tapwater in their reef?

I used to be on well water and had a water softener and my tank did well. I used the water softener salt you get from canadian tire.

soft water will in no way hurt your tank (it just has lower hardness and calcium levels then untreated water. which is good for everything in your home except the tank).. just use it like you would normal water and add a bit more kalk to your top off and you will be good.

did you know that r/o water is better for your tank??

Test your tap water water for phosphates, nitrates, and copper.
