Hello all,

Haven't posted in a while. Trying to help my neighbor out. He had a big get together over the weekend with 3 days of swimming with 25 people or so every day in a 17k gallon pool with 105 degree days each day. So needless to say his pool was VERY VERY cloudy. I went over yesterday and checked it has ZERO Chlorine, He also said he dropped his PH way too low 2 days ago to around 6.2 so we raised it with baking soda to 7.2. Then checked TA which is at 70. I add 1.5 gallons of liquid chlorine after PH got to 7.2. This morning checked again, Chlorine at 5ppm and PH @ 7.5. Spoke to neighbor and he mentioned that he put a bunch of conditioner in 2 days ago as well..... question is what can happen if TOO much conditioner is in the pool ? Can that cause cloudiness? I'm aware that if CYA is too high then draining water will need to happen. Water is cloudy still though there is a noticeable improvement. He did say he cleaned his filters a month and a half ago. What to check next? Thanks!

**Forgot to mention that this is a 17k gallon SALT Pool, cartridge filter, small waterfall, 6.5ft deep end.

Hi there, By acid I assume you mean PH? PH of 7.2 and TA of 70 should be ok but the most important thing right now is to get chlorine into the pool and keep it there. That 1.5 gal of chlorine will likely get consumed rapidly so you'll want to test frequently to ensure its not getting consumed and your back to 0. As Texas Splash has stated, SLAM is most likely the best path forward here.

Ya sorry about that typed in a hurry lol. PH is correct. So I did the SLAM yesterday around 3:45pm and the readings today are what I got. How long does it usually take to clear? He will be home soon, so I told him to take water to pool store to check CA as I'm thinking he may have to much after he told me he added a bunch of CYA. But currently Chlorine holding stable at 5ppm and PH 7.5. Anything else I can check since I did the SLAM? Thank you BOTH again!

You might want to read SLAM Process
It is NOT a one time addition of chlorine. It is a process, over several days to week

Ya just read it. Also, just got back from pool store testing water attached and here are the results:

Free chlorine: 4.99
TOTAL Chlorine: 4.99
PH 7.6
Total Alkalinity 86
Calcium Hardness 191
CYA 45
Salt 2579

So on that not CYA can come up a little more right and then salt to 3200 ?

Thanks again!

Can you test the CYA? To be honest, we do not provide guidance on pool store tests.

IF the CYA is correct, leave it until you can test it and sort out the SLAM.

Questions and I assume the answer is NO, but he wanted to have people over tmrw to swim....I told him NO as chlorine levels are really high for the SLAM that we started yesterday. He asked me how long it would take and I told him a couple days to a couple weeks depending. Was I wrong? Thanks!
 
They can swim at SLAM level based on a known CYA as long as you can see the bottom of the deep end.

Oh ok good to know we can see the intakes at the bottom of the deep end, cloudy somewhat but you can see it now. Also, he asked about his Phosphates being REALLY high I told him not to worry about that right now. Correct or ?

Correct on the phosphates. You have to eradicate the algae before dealing with those, if necessary. Need a phosphate test kit (the pool stores will panic with a level that is not a big deal). K1106. If over 2000 ppb then a treatment might be necessary.

First deal with the algae.

Agree. Can you use your test kit or encourage your friend to get one? It will make providing guidance easier since the pool store tests can be a hit or miss.
 
It also strongly suggest that my first post I mentioned I tested the water yesterday and posted my results. Today is another day, I tested again and then went to pool store to be sure my testing showed somewhat same results and it did. That's all.
 
For good reason, folks here put near-zero stock in PS results. I understand the feeling that sometimes I need to validate my readings. I used to do that. But I stopped doing it when I realized that it was a fools errand. The PS results were al over the place. Now if I question my Results, I just repeat them. Posting PS results here, particularly when mixed with K2006 results, will just have everyone running around in circles. In any case, I’d suggest to only post results from your kit; hopefully we can return to the task of offering excellent advice.
