thought I was a veteran pool owner

Until I tried to open my pool this spring. Thank God I found this forum. I have been using dichlor granules for the past few years and noticed over time it was getting increasingly more difficult to keep the water balanced. I now know why. I've spent this week partially draining and refilling my vinyl inground pool. I am finally getting to around 100 on my CYA reading and don't know if I can afford to keep running the water much longer. Is there any other possible way to keep lowering the CYA without draining?

Thanks, this forum has opened my eyes to the truth!

You might check out the Bio-Active threads in "The Deep End" part of the forum.

It's a new kind of CYA reducer. Some have had success, others not so much ,but it seems to be cheaper
than drains/refills for some of us.

It reduced my CYA from 100 to 80 in 5 days and still has a few more days to go.
