What is BAN? Is that your abbreviation for Backwashing Acid Neutralizer?
Yes, that is correct.
Here are pictures of after my Dad and I finished installing:
I think we over corrected the pH though
The water sort of has a slimy feel to it and the cheap inaccurate pH strips are indicating the water is very basic. One of the BAN tanks has 1/2 cu. ft of Corosex which is probably why. Luckily, we installed bypass valves on each so I can mess around with bypassing that tank to see what types of results I get. I am going to get water tested today at pool store to see where we stand. Total mixture content = 2.5 cu. ft of calcite and 0.5 cu. ft of Flo Mag (corosex). However, I did not let everything backwash completely yet due to time restrictions and the backwashing cycle is set for once every three days...going to monitor the water throughout the week.
pH level measurements at pressure tank before installation:
Pool store: Less than 6.2
Dad's friend who performs work on cooling towers (commercial grade equipment): 5.2
Cheap inaccurate pH testing strips: 4-5 (pH of approximately 4.5)
pH at kitchen sink after installation of new equipment:
To be determined
