Hi,
I got a report from the pool store when they tested my water and
said my acid and total hardness was low.
Of course, they want to sell me all kinds of expensive stuff. I am
trying to find out if I can use something cheaper that works.
They told me to add stabilizer for the acid level and a balance pak
for the hardness.
What can I use?
Thanks for your help! I am still trying to get it together so it
won’t be so cloudy too.
