I was reading another article about phosphates and one of the suggestions in limiting them and other containments would be to use an rv filter. Just wanted to see if anyone has noticed a difference if they have gone this route or just a waste of money.
For clarification this is not to fill the pool initially but to add an inch or two after evaporation. Thanks all. Appreciate the response as I’ve learned so much on this site.
