I have 2 sons who are lifeguards at our local city recreation center pool. The other day, the pool was shut down because the FC level was above 5. (They tell me it was 10 because the automatic chlorinator was left running the previous night). The day after the shut down, the pool was...

FC at 5:45pm was 12.2. CC=0.6. Is there a maximum safe level of FC? (In other words, if the FC is above _____ , then I should not be in the pool?)

I may choose to restart the slam..... after the 4th of July This morning my CYA is around 55. TA=110. FC=19 and CC=0.6. I've kept the FC up to as high as 27 yesterday, but the CC has remained at 0.6 for the past 60 hours. I intend to let the FC drift down and start using the pool for the...

At 7:30pm, after a rain storm, the FC=16.6 and the CC=0.6. Still not below 0.5, so I added 2/3 a bottle of bleach. I'm hoping that the CC will be down to 0.5 or lower sometime this evening, and then I can try for the OCLT in the morning. Question: If CC comes down to 0.5 or lower, and I...

jon, if I have an FC=21 and use the 25ml test, it would take 105 drops of the reagent. How many drops of the reagent are in an ounce?

5 hours later, my FC=21 and CC=1.0. I'm not doing the 25ml sample of water with the FC so high. The CC has been between 0.8 and 1.0 for the past 46 hours. Does it always take so long to get rid of that last thousand parts per million of combined chlorine? Should I add another 11 ounces of...

My CYA is now 55 (half way between 50 and 60). The FC=12, and CC=0.8. TA=110. I've adjusted my target shock level to 22, and added another bottle of bleach.

I was changing the filter cartridge and "backwashing" last night. When I was done, I needed to add a little city tap water to the pool to bring it back up to level. How will this affect my slam process?

OK. So this morning the FC=14.5 and the CC=1.0, and I poured another bottle into the pool. This evening the FC=19 and CC=1.0. Another 1/2 bottle of bleach with that. I'm wondering about all the trees in my yard, with all of the debris that falls into the pool. Would this cause the CC to be...

I picked up some R-0871 from Leslies pools in Bensalem PA

At 7am this morning, the FC=13.5 and CC=1.5. I dosed another bottle of bleach. At 5:30pm the FC=14.5 and CC=1.0. I dosed 113 oz of bleach. I may not be able to measure the chlorine again until I get more R-0871 reagent. I hope to pick some up tomorrow afternoon. It would have been nice to...

AT 7:30pm the FC=20.5, and CC=1.5. I added 1/3 a bottle of bleach. That makes 34.33 bottles of bleach in 75.5 hours, in case anyone is wondering. With tax that comes to $100.80 in bleach alone.

At 6:30pm the FC=24.5 and the CC=1.5. I've finally reached the shock level!!!!!:D .....what do I do now?:confused:

At 5:40pm the FC=5. I dropped another 1.75 bottles of bleach.

This morning at 7:30am the FC=2.5. I added another 2.25 bottles of bleach. To answer James W..... None of the bottles that I poured into the pool said anything about acid. I'm off to work.

At 12:30 the FC is still 16, but the CC=3!!!!!(6 drops). I added another 0.75 bottle of bleach and am calling it for the night. We'll see what the morning brings.

At 12 midnight, the FC=16, and I added 0.75 bottles of bleach. The TA is holding at 110, and the pH is at 7.3. I just hope I can function at work tomorrow. ...and I removed Leslie's chlorbrite from by signature, and replaced it with liquid bleach.

Just finished ordering refills from amazon. Should I check FC again after 15 minutes of the latest bleach dose.

It's getting late for me, but..... I added 2.5 bottles bleach at 11:10pm. At 11:35, the FC=12.5!!!!!!!(that's 25 drops.... I may run out of reagent before I finish slamming). I'm going to add another bottle bleach now.

Pooldv...... thank you for the support!!! I will keep trying. I added baking soda at 9pm. At 9:30pm the alk was up to 60. I had to go out to buy the borax. I added 130 oz (2 boxes) at 10:30pm. How long should I wait to test the pH? Also, if there is ammonia present, should I do anything...

Should I get pH and Alk back to a certain level before continuing slam?

I have a trichlor puck in the floater.... I added dichlor shock (chlorbrite) a week ago. Prior to that the CYA was between and 30 and 40. After that it was 70, but now CYA is at 60.

pooldv..... so you think I should continue slamming after I get the alk and pH back up? - - - Updated - - - I have a trichlor puck in the floater.... I added dichlor shock (chlorbrite) a week ago. Prior to that the CYA was between and 30 and 40. After that it was 70, but now CYA is at 60...

Re: I've slammed for 48 hours and 26 bottles of bleach but...... When I started the slamming process, the pH was 7.2 and the alkalinity was 90. That was 2 days and 26 bottles of bleach ago. I'm usingTAYLOR TECHNOLOGIES INC K-2006 TEST KIT COMP CHLORINE FAS-DPD. I bought it on 06/20/17 via...

I've slammed for 48 hours and 26 bottles of bleach but...... I've slammed for 48 hours and 26 bottles of bleach. I haven't been able to get the FC above 6, and that was only in the 1st few hours. After that the FC hasn't been above 2, and for the past 13 hours, it hasn't been above 1. The...

I'm usingTAYLOR TECHNOLOGIES INC K-2006 TEST KIT COMP CHLORINE FAS-DPD. I bought it on 06/20/17 via amazon. Tonight I used the 10ml sample. I use the scoop provided with the DPD powder (R-0870), using 2 scoops, but tonight the sample remained clear, so I added a 3rd scoop, to get a pinkish hue...

This morning at 7:30, the FC=0.5, and I added another 2.3 bottles of bleach. This afternoon at 5:50, the FC was less than 0.5. I am 49 hours and 26 bottles of bleach into it, and still have FC that is getting lower and lower. The CC=12.5. I feel like i'm throwing good bleach after bad. The...

And at 10:50pm, the FC=1.5..... and so I added another 2.25 bottles, making the total at 23.75 bottles of bleach (but who's counting.... right???!)

I retested the CYA at 6PM today, and it is still 60. So, from 4pm yesterday, to 6:15am this morning, I dumped 12 bottles of bleach. At 6:05pm today, the FC=1, and I dumped another 2.5 bottles. At 7:20pm, FC=1 again, and another 2.5 bottles followed. At 8:30pm the FC=2, and 2.25 bottles...

At 06:30am the FC=1.5, so based on CYA=60, I dumped another 2.3 bottles of bleach. Something is eating up the bleach overnight.
