Green, green, green and running out of patience.

You are doing very well! Keep adding the bleach. You lose bleach during the day to sun light which is why we suggest testing in the evening (as a base number) and in the early morning for the comparison number. Don't worry about the difference in CYA. That's a very subjective test and yes, the lighting when you read it has much to do with it. + or - 10 points won't make a difference in how we need to treat the water anyway.

There will come a morning when the difference in FC readings is 1 ppm. Or 0 ppm difference from the night before. That's the day before the day you're done adding so much bleach. It'll happen soon now. The water will look blue but will probably be cloudy from the DBs. The dead algae bodies And your CC will be .5 or even 0. It can take 6 days or so to get the green out and then another 10 days, sometimes longer, of constant filtering and brushing the bottom to clear the cloudiness. A long time, I know, and we've all gone through it. The good part is that we are not polluting the water further by throwing chemicals at it that don't work any better or faster than the bleach but that do cost a whole lot more.

Great job on the pH testing! And the improv on the skimmer 'sock'

If you haven't already, would you please fill out the PF Pool Chart Form (see last item in my signature)? It asks for information about your pool and the equipment you have and is a source of reference for us when we need to devise a solution to a problem your system may have.
