New pool owner for the second time...

11 lbs. of stabilizer will add about 40ppm of CYA. Take out the nature 2 cartridge. Follow Ben's directions above.

I added 1.5 gallons of 101 bleach (some brand at Wal-mart). tested in corner of pool and got .4 PPM FC and .8 ppm CC. I assumed my CC would have been 0 earlier when the sample did not change colors at all when I added the 2 scoops. Guess I was wrong. I was expecting about 2.4ppm based on my size of pool if the bleach was 6%. May not be 6% bleach or bigger pool or already used up due to some green stuff present.

Most likely it was used up if you have green stuff present. To clear up the green stuff, you need to get your chlorine up to the 12-15 ppm range and hold it there until it clears, filter running.In a 36K gallon pool, each gallon of 6% bleach should raise your FC by 1.7 ppm, so you can use that as a guide when testing and adding more bleach to get back up to the shock level.

I think I read somewhere else on this forum that the 101 is 3%.

I think I read somewhere else on this forum that the 101 is 3%.

based on my most recent tests I would believe that is true. It is also just slightly less than half the cost of 6% bleach. So I could just buy twice as much. Thanks.

Thank you Janet. I will start to work the Cl` levels up.

water is crystal clear today after Irene visited last night. I had to do some vacuuming this morning to get the leaves out. Now I am sitting around
4 ppm FC
0ppm CC
PH 8
TA 100
CH 190
CYA 60

Will add a gallon of 12.5% tonight after sun goes down. I used 3 gallons yesterday to get ready for Irene, Cl` was around 10 when storm started. Pool level raised 2 inches.

Based on the best guess chart I am low on Cl`. Should I add the gallon now in the middle of the day? Sun is out pool is open. Water temp is probably low 80's.

Thanks,

Since you're low for that CYA level, and since hurricanes bring all sorts of nasty stuff with them, I would add your chlorine now, instead of waiting for tonight. However, honestly if it were my pool, I would just wait and shock the pool tonight to kill off whatever Irene brought with her.
