Sorry for the delay....been stupid busy all day with house stuff.

I found a few things that might help? forgot I had this, but picked up a 3 gallon jug of 10% chlorine the other day for the house water system. It doesn't need any at the moment, so I'm assuming I could use that?

Also found a packet of "Power Powder Plus" - label says 73% Calcium Hypochlorite.....minimum 70% chlorine and as best I can find online it doesn't have any stabilizer in it.

My test results are puzzling to me. It appears as though my CYA has actually risen ?!? I've added nothing to the pool other than the generic 8% bleach since we began this dialogue. It's been raining on and off today, little to no sun.

My CYA level measured out to be just above 100.....with the half solution !?! The full strength test showed the amount of solution to see the dot to be less/high test result.....but off the scale.
PH 7.6
Alkalinity 130
Calcium 320

FC .2ppm



Should I get the hose out and start draining like half the water?!? Or add the chlorine and shock that I have now? The algae that is on the bottom is as you describe it above.....brushes up easily and clouds.

==============================

Just read more on the CYA test.....I've been doing it on the dark counter top in the kitchen. Holding it up with an ample amount of light to see I get 80 with the half test so 160. Coincides with Ben's estimate of ~150 (what...you've done this before ? )

Sorry for the quick follow up post....I just was eager to post the results without studying the test procedure adequately.

I'm assuming I continue with my course of action - chlorinate!
