THANKS!!!

Checked sample inside 75 degree home 2 to 3 hrs after taken from pool at temp of 66. Slammed night before with 5 gallons of liquid chlorine (10.5) after pool showed CC of 1 and FC-.5 I know this was about a gallon too much chlorine but I'm getting ready to close and decided to use all of the...

Thanks for the advice!

I opened 4/29/16 and pool was and still is clear. FC 3, CC .5, pH 7.8, TA 120, CYA 40, CH 200, Temp 72. New vinyl liner installed end of last summer. I know I need to add a little chlorine. Should I try to get my CH up to 250 as TFP recommends 250 to 400?

Thanks for your help! My CYA is 40.

My FC was 1.5, CC-.5, pH-7.8 before I put my maintenance dose of chlorine in. I was aiming for FC of 5 and got 6.5. Do you think the maintenance dose (140 ounces 10.5 chlorine) caused the pH rise? I guess I'll know the answer to that if it doesn't drop in the next couple of days.

I know I shouldn't close my pool with the pH low, but will it hurt to close with it high? I've put a couple of gallons of muriatic acid in and aerated to get my TA down to 120 in the last 2 weeks, but the pH drifted back up to 8.2 from 7.8 when I put my maintenance dose of chlorine in. My...

FC 7.5 CC .5 pH 7.8 TA 130(pink) 140(red) again CH 175 CYA 40? I added a half galloln of muriatic acid after my last post and the pH came down to 7.5. A few days later, it was back to 7.8. I put half of the remaining half gallon of acid in and it returned to 7.5 again. A few days later I put...

Thanks for the pH and slam advice Dave. After looking at Marian's question, I realize I mistakenly posted my FC as CC. Sorry for the confusion. I assume I should still lower my pH and ignore the slam. Sorry for not posting all my #'s. The pool hasn't run for 3 hours but i went shoulder deep...

After adding 2 gallons of the liquid stabilizer, my CYA is now 40. Thru this 3 or 4 day process my pH has gone from 7.8 to 8.2. My CC is currently 3 and my TA has been in the 150 to 160 range since the pool was refilled. Water temp is down to 74 degrees and the pool looks good. Pool business...

Instant Pool Water Conditioner by Natural Chemistry

I just bought some liquid CYA that is 35% Monosodium cyanurate monohydrate and Percentage of Constituents Ineffective as Spray Adjuvants 65%. It's equivalent to 30% cyanuric acid. The product says it is a salt and not an acid with a pool friendly pH, so it will not damage pool surfaces or...

How long do you have to wait for an accurate reading after adding the liquid form of CYA? Just curious as I haven't bought it yet.

Thanks, I'll be looking for some liquid CYA.

Thanks, I never thought of it but that makes perfect sense! Any suggestions on the chemicals?

Test Results At 10AM, 9/11/15. FC-.5, CC-0, pH-7.8, TA-160, CH-175, CYA-?. Tested 12 hours later after after adding 1.25 gallon of liquid chlorine (sodium hypochlorite 10.5%) and only change was FC-6, CC-.5, CH-200. The pool leaked an inch of water roughly every 12 hours for 6 days after the...

thanks for the advice on the walls and steps!

I forgot to mention that I have a large oak tree growing close to the pool with finger sized roots visible beneath the liner on a side wall. I would really like to leave the roots alone as this tree is already stressed with the heat we are experiencing now, anthracnose, and striped oak worms...

just patched a tear in the corner at the waterline of a 12 yr old in ground liner. sure i'll have to replace soon. this is our second time replacing the liner. advice welcome.

Thanks again!

Thanks! Seems I've read that it can take a week to get an accurate CYA reading after draining and refilling. Is that correct?

Any suggestions on how far to drain this 12 year old faded out liner. I'm hearing a foot below the skimmer to a foot in the shallow end. I started yesterday pulling from the main drain with 2 hoses filling at the same time thinking I wouldn't be pulling the fresh water. I've been told a foot...

THANKS! I'll be shooting for 50.

FC 12.5 CC 0 pH 7.5 TA 110 CH 225ppm CYA 110 Water clear since initial 4 day clear up after opening 5 weeks ago. I'm going to drain some water off to get my CYA down so I can quit using so much chlorine. Suggestions welcome!
