CYA Low 90/100 Yeah I Said Low! Now My FC Is Going Bye Bye...

Plus, all that organic debris in there (leaves, twigs, dirt, etc.) also causes you to use more chlorine.

ok... looking back at my pool log i vacumed all the debris and goo out of the pool on 9-3-12 about mid day ( finally had the time ) and also cleaned out the filter which was pretty dirty. i then measured FC that night ( 6:30pm ) and got 13.5PPM i then added 3 qtrs of bleach which should have bumped me up to around 19.5PPM. i measured again on 9-4-12 at 7:00pm and got 13PPM which was a loss of 6.5PPM in just over 24hours.

i tested this morning at 7:45am and got 12.5PPM, so i only had a .5PPM loss last night. after this test i added one trichlor puck in the floatie to get some of my CYA back, and add some FC. i just tested and had 12.5PPM FC and 0 CC, so it seems it may have just been a matter of getting all the debris and goo out of the filter and hitting the pool with a nice dose of bleach after the clean up.

just for good measure i just dosed with 7 qtrs of bleach which should get me up to around 26.5PPM. now i need to run out and get some more bleach since i only have about 1 qrt left...lol

im confident my CYA test the other day was accurate, so ill measure again after the trichlor puck has disolved and add another if needed to get me back to my " sweet spot "

funny thing is none of our rainy/windy summer storms have caused me such a chlorine demand, even when it was blowing debris into the pool. must be something special with hurricane storms.

thanks for the input guys and gals!
