Hi,

I had a serious green algae problem that finally subsided after six gallons of chlorine, brushing and numerous pool & filter cleanings. Unfortunately, my pH levels went way down and the upper 8" of my vinyl liner turned brown. Concerned about damage to my machinery, I stupidly added two pounds of sodium carbonate (all at once) to the pool to raise the pH. It didn't dissolve well and the majority of it ended up on the pool bottom as a blue silt. Now when I try to vacuum, it just runs through the filter and blows back into the deep end of the pool.

The chlorine level is off the charts. pH is up to 6.8 but I can't get a TA reading with my kit (water goes yellow but won't go red) and this worries me. I'm afraid to run the filter 24/7 if my equipment is at risk. Should I anyway? I'd appreciate some suggestions.

Thanks
