My old Braswell system needs to go. It was simple and fairly reliable but while I was away for the holidays the freezing weather split my media tank and killed the valve. Aquasure looks cool but I won't say that A word anymore. So where can I go to educate myself on choices and sources with Clack and Fleck? This is for a well system using a 948 tank. I'm going to send a water sample off this week for testing. BTW, since KER Labs is history for water testing is there an alternative?
