Did a little reading today and bought a test kit on the way home tonight.
CYA was WAY over 100. I didn't even have an inch in the clear vial and I couldn't see the black dot.
So, I got 9000 gallons of water running down the street and plan on refilling tonight.
Hopefully that will bring them down to a reasonable level. Planning to go the bleach route when I get them to a normal level.
Any other suggestions besides quit using that $200 worth of useless tablets and shock I just bought?
