So if MPS is a waste of money.
I have only ever shocked with chlorine in the spring and fall (5 lbs) which costs $30-50 (I can't remember)
The rest of the time I drop 2pounds of MPS to drop my combined chlorine by 0.2 for $5 then drop 2 pounds of ph up to raise ph 0.2 for $4. So for less than $10 I fix my chlorine problem, can swim in 10the minutes, and don't have to worry about turning off my copper heater.
how does bbb shock work?
What are the costs?
Do I need to worry about my copper heater?
What am I missing?
Sometimes I wish I was a chemist.
