Chlorinate pool with liquid 12.5% Sodium Hypochlorite. Interestingly, I was using a chart I printed off when I started BBB in 2014 that shows a target FC level of 5 for CYA 40. I will now use the newer chart and raise my levels. Temp is 88 today. The cover is on when not in use which probably...

I've had an odd summer when it comes to my pool chemistry. I've battled what I think is an algae problem all summer - I have the brownish residue that disappears when swept (see pic). I brought it up to SLAM levels several times and passed the test but I continue to battle the brown residue and...

This is my 6th summer using the TFP method. I am starting day 5 of a SLAM due to brown "dust" (algae) on bottom of pool and along seems and in wrinkles on stairs. I am brushing and using Dolphin to clean everyday and backwashing when needed. Water is crystal clear (see pics). I cannot find the...

Hi - I'm helping a friend who follows pool advice - they are willing to try BBB to get their cloudy water in check. I tested for them and here are their numbers: FC = 5 CC = 1 PH = < 7.0 (PROB 6.9 OR 6.8) CYA = 70 TA = 180 I am going to advise him to bring up ph and then bring FC...

Thank you for the information!! That was the only time I've had PS test this year - I am completely BBB and love it! My levels per my kit: FC 5.5 (I added bleach this morning to bring to 8) CC .5 PH 7.6 TA 125 (still high from PS bad advice 2 years ago) CYA 80

I had my water tested at the pool store and according to them, my hardness is 316 and they suggested adding 3 qts Scale Inhibitor. I have a vinyl lined pool. Is this necessary? When I test with my Taylor kit I get around 200 but I don't regularly test that because I didn't think it was...

This is my first full summer with the BBB method. Last summer and earlier this summer, my CYA was high so I didn't have to add as much chlorine. My CYA has now drifted down to 27 (per pool store/40 per my test kit) and I feel like I am adding chlorine a lot - I usually add 2 bottles a day and...

This is my second summer with the TFP method. I have some scaling and high TA and wondering what suggestions are out there. My numbers: FC = 6 CC = .5 PH = 7.4 TA = 150 CYA = 50 CH = 175 (pool store hardness sample = 354) I have a vinyl liner, so I thought the CH doesn't matter that much...

I live in an area that freezes and must winterize my pool. I've followed the BBB method all summer with great results! After researching winterizing, I have a question about chemicals - one place I read said to bring it to SLAM level and close and the other place I read said to bring it to...

Water looks great. Just using up chlorine... Here are my numbers: FC = 8 CC = 0 PH = 7.6 TA = 250 CYA = 70 I don't test CH because I have vinyl. Filter pressure is running much higher than normal and new crackling sound leads me to think air is getting in...?

I am new this summer to the Trouble Free Method, so I am still learning. With that said, I'm not sure if I should SLAM or not... I am losing chlorine overnight - last night was 2ppm. The water looks clear but there is a gray 'powdery' looking material on the bottom - even after vacuuming...

I just completed my first SLAM after 2 partial drains to reduce CYA. Got my cc down to .2, water is clear and passed the OCLT test. However, my CYA has increased the past few days after only using bleach for chlorine. I did have some old silk tabs in my feeder but the feeder was dialed to the...

I just completed my second partial drain and refill due to sky high CYA and TA. Here are my new numbers: FC = .4 CC = .4 PH = 7.6 TA = 275 CH = 175 CYA = 55 The water has a greenish tint to it after refill. Do I need to decrease the ph more before beginning the SLAM process? Approximately how...

Re: 2nd Drain/Refill - New Numbers @sbcpool - I had to do the alternate CYA test with partial tap water and multiplied by 2 to get 72.

I just completed my second partial drain and refill due to sky high CYA and TA. Here are my new numbers: FC = .4 CC = .4 PH = 8 TA = 320 CH = 225 CYA = 72 The water has a greenish tint to it after refill. What should I address first - PH or chlorine? Thank you for your advice - I am new to...

Re: Drain/Refilled - New Numbers - now what? Does it make sense that it did not go down after the drain?

I drained and refilled 40% of my pool to reduce my extremely high CYA, alkalinity and chlorine. However, my CYA did not go down that I can tell! What is my next step? NEW NUMBERS FC = 9 CC = .4 PH 7.8 Calc = 210 TA = 325 CYA = 150 - 'Guesstimate' because black dot disappears so quickly...

Ok - I will try to clarify a few things! TODAY I determined TA by taking a 10 ml sample and adding 1 drop R-007, 3 drops R-0008 and had to add 21 drops of R-0009 before it turned red. I multiplied 21 by 25 and that is where I came up with 525. (Directions for when high TA is anticipated)...

I received my Taylor K-2006 and here are the results: TODAY/YESTERDAY FC = 20/32.5 CC = 1/0 PH 7.6/7.6 Calc = 325/ 325 TA = 525/550 CYA = 150/150 - 'Guesstimate' because black dot disappears so quickly. Let me say, I am a total novice! Pool is 6 years old and we've...

So confusing!! So now my TA is way too high? What do I need to adjust and in what order and how?

Yes, 25 ml changed from blue to yellow only. Calcium = 325

Got my new Taylor k-2006 and tested today. Here are the results: FC = 32.5 CC = 0 PH 7.6 Calcium = 325 TA = ??? For TA I followed the directions using a 25 ml h20 sample. I added 250 drops of R-0009 (not kidding!) and it never turned red. I decided to try it with 6 ml's of h20 and it...

I did a TA on my tap water and got the water to turn red. Instead of 25 ml's, I did the TA test on 12.5 ml's and also 6 ml's of pool water and used the same amount of reagents. I could not get either to turn red after 100+ drops of R-0009.

Yes - pool liner was replaced last summer! Thanks so much for finding that @scuba_steve! Opened about a month and a half ago but haven't swam it in since. Algaecides - just weekly maintenance dose except for adding 16oz this past Tuesday. My chlorine is high so not sure I should...

Here is the latest weird twist!! Kids were swimming and the bottom of their feet get an oily black residue all over the bottom. Hard to scrub off - almost like tar. Sometimes when I brush, I can see black particles disperse. Pool co did test for black algae and said not there. Any ideas?

Yes, auto cover. It is usually kept covered. Water is beautiful. Kids are swimming and say their eyes do not burn at all.

I ordered a kit and will wait for that to get here and update my numbers. As for drops added, I just redid it and stopped counting around 90 - still no change! Should I leave the pool open to burn out some of the chlorine or is the CYA too high to allow that to happen? I haven't added...
