Phosphate problem off the chart

[fmblizz]

Thanks Needsajet

I am in great shape I feel... The water has been crystal clear for a week now and the ph is on target.. Since my CYA is at 70ppm I have been targeting my FC around
the 8-9 ppm level and things all appear to be fine. I see you were referring to the Shock level but in my situation, I'm pass that stage but if needed I probably would play it safe and wait a day or two for the Shock level to drop nearer to my Target FC level..

Excellent! I was answering your question regarding the safe range for FC.

For 70 PPM CYA, the water is safe for swimming when FC is 5 to 28 ppm, provided that your pH is within the recommended range.
