HI Everyone!

Thanks for the great replies. Today I added a total of 3 gallons of liquid chlorine shock and one calcium based powder shock. I also brushed 2 times. This seems to have the algae in check so far. I will definitely keep up the chlorine levels and will keep BRUSHING, BRUSHING AND BRUSHING!

I went to our local pool store and the drop test only read chlorine levels up to 5! I ended up getting an advanced type of strip test and here are my results...

Hardness-400
Free Chlorine-higher than 10 (very dark purple!)
pH-7.6
Alkalinity-180
cya-30-50 range

One question still...What is polyquat???

Thanks again everyone. Hope you are all enjoying clear, warm, algae free water in your pools...

Have a great night,

Sue
