Just added about 1.5 pounds of granular CYA in a sock. I wanted to be conservative on the first addition. When should I check the CYA level again? 24 hours after completely dissolved?

Excellent. Will add it tonight.

Just ran some tests: FC 6 pH 7.5 TA 140 CYA 26 CC 0 I’ve got some Trichlor pucks available as well as some granular CYA. Expecting some swimmers today and tomorrow. I am burning through Bleach like it‘s nobody’s business. I definitely need to add some CYA. How best to do it? Slowly with the...

Did the OCLT last night. My FC loss was 0. CC was 0.5 using the 10 mL test. Water is crystal clear! SLAM method worked wonders!

1 ppm (FC 19 -> 18). I was a bit lazy and tested once it was light but just barely. Didn’t test my CC because I forgot. Will test them this afternoon. They have been 0 the last three times I’ve test this week.

I have been using 7.5% liquid bleach. I have some Trichlor pucks but didn’t want to use them Unless advised. I’m aware of high CYA issues of the pucks. I am researching SWCG currentoy but wanted to get my pool in tip top shape before doing so. Will do a CC this afternoon. How much FC...

Water is as clear as I have seen. FC has been 18-19 for the last 12 hours without adding any bleach. I’ll see what my FC does throughout the day and decide on an OCLT tonight into tomorrow morning. Agree?

Another good day. FC has been at SLAM level the entire day. Have been through about 3 gallons of 7.5% bleach today. Water continues to look great. Brushing and robotic vacuuming are continuing twice daily. Hopeful to wrap the SLAM up by early next week. My CYA was hovering at around 30...

Excellent plan. Have been doing that since last night. I ordered some more reagent off Amazon just in case. Thank you.

Excellent. Will do.

SLAM is back on track! PH has drifted up to to 7.7ish. Added muriatic acid to get pH to goal of 7.2-7.5. FC has been 13-19 all day long (6 checks). Water is clear and spirits are high. Curious to see what the AM FC will be. Full set of tests coming in the morning.

I was reading the wrong chart. Silly me. Read the article. Added enough bleach to get FC to 16. Will recheck FC in 20 minutes. Thanks.

Retested my water before sunrise today. Water is very clear and looking great. I am very uplifted and encouraged (more importantly, so is my wife)! Results: FC 6.5 (around 8 yesterday before sunset) pH 7.4 TA 190 CC 0 CH 375 CYA 30 SLAM is nearly complete. I just need to pass OCLT which I will...

Rechecked my chemistry after adding 25 ounces of diluted muriatic acid 3 hours ago. New results: FC 8.5 CC 0.5 pH 7.35 Pool is cleaner than this afternoon. Planning on leaving everything as is and rechecking everything in the morning unless anyone feels the pH needs to be lower.

Got my TF-100 test kit in today and used it right away. Water is much clearer but not crystal yet. I have been putting liquid bleach 7.5% daily and my test results are below. Filter has been running 24/7 for the past 4 days. Have brushed and robotically vacuumed twice daily for the past 4 days...
