Thanks. Yes and No - we are still dealing with our problem.

We've lowered the water level three times on the pool to get the cyanuric acid down 55 ppm so far. Would like to take it down further, but summer is slipping by and the kids want to swim. We are completely switched to the grocery store chemicals now. We are simply super chlorinating to clear the pool, and running the pump on high 24/7. The color of the water has switched from green to brown to light green to now it is cloudy white and blue. So we are hopeful we are headed in the right direction. Our other problem is that our TA is 210 ppm with pH at 7.6. We've tried muriatic acid in the middle of the pool without the pump on (it lowered TA from 240 to 210), but it lowered the pH to 7.2 as well. On a low Cl day we let the kids splash around in the pool to aerate it and try and bring the pH up so we could hit it with another muriatic acid dose to bring TA down. That worked so far. Anyway, we just live with it the color it is, hoping it will clear up soon...
