I have been running my fountain a lot the last week. Temps in the mid 90's, pool mid 80's. I keep my TA around 75 to 80 and get very little ph movement. That changes when I run the fountain. Now that I am testing ph more I ran out. Sent SWMBO to get somemore. She came home with a new bottle of R-0014. The k-2006 had R-0004. Will I get different results with this?
