Just back from a few weeks abroad, and these are my readings. I’m not sure if I need to mess with this as the CSI is fine. I’ve turned of the chlorinator for now, but my CYA is usually around 60, I keep my TA at 60 and Ph around 7.8-8.0 during Florida summer months and water temp at 88-89 as...

I have been away two weeks and using water guru to test for FC and Ph each morning. These two readings are accurate in the new Sense 2 model. I want to know if I need to get my wife to add MA to lower the Ph which has risen to 8.2. And if so what do I lower it to? My CSI is great as it is...

FC has become increasingly more difficult to balance since a bag of salt dropped in a couple of weeks ago caused it drop overnight. I discovered it immediately, topped up FV and It passed the OCLT at that time, but I’ve noticed my SWG is not working as it should. Super chlorinated for 24 hours...

How long does it take for borates to reduce? I added 40 level to my pool a couple of months back, but am worried about my dogs. So I’m not going to add it again. My dogs rarely swim and don’t have access to the pool to drink from it. But they are only 14 pounds and I’m second guessing my...

Yesterday I put a bag of salt and 68 oz of muriatic acid in the pool. Had to drop the TA. Also had the salt cell replaced early afternoon yesterday. FC dropped overnight to 1! I just checked the water coming out of the return - it tested at 3 so the salt cell is producing. I’ve dropped some...

I just changed from a Hayward t-15 to a 940. Do I need to change pool math/TFP profile to reflect that change?

Last week I had some flakes with a TA of 80. I was advised here to drop it to 60. Did it and flakes disappeared. Great. But the TA just tested at 80 again! I have added water to the pool twice this week as zero rain and extremely hot. I just added acid to lower the Ph back to 7 and will get...

I just noticed white flakes in my pool. I super chlorinated this morning for 4 hours. We were in the pool yesterday and they weren’t there. I checked the SWG, it’s clean. I checked the filter (cleaned a few days ago - still clean, but I swapped the cartridge anyway). Pool is balanced - tested...

I introduced borates yesterday. Pool math told me to add 29 lbs I accidentally only ordered 25 pounds and added all of that. Test strip is reading just slightly darker than 50 but very close. My Ph is 7.3 as I lowered it as per TFP instructions. Just wondering if I should add 46 ounces of...

I seem to be losing close to 10ppm of CYA a month/6 weeks. My pool is warm at about 86 and we haven’t had rain in ages so I’m topping up a couple of inches a week. As far as I can tell from reading, this may be normal. I just wanted to confirm I’m not doing anything wrong. I increase it to...

Hi there I have solar on my roof so want to run my variable speed pool filter only during daylight hours. I also dislike the sound of it on high. Hayward told me I have to run it on high for four hours and then on low the rest of the time. Is four hours a hard and fast rule? 12200 gallons...

Hi what’s the difference between my main drain and pool return? Which one do I turn off when adding salt?

I had an Omni attachment out on to my bubbler. The guy who installed it has the feature too high for my liking. How can I turn it down? I just want it to work in less speed than it is now on all filter settings.

I’m slamming yet again as I was losing FC despite the water being crystal clean. So I did an OCLT and it failed on Tuesday night. I’m now ending day 3 of SLAM but the pool is still losing FC. Add to this so much rain at the moment - I’m going to have let some water out again. Just tested...

Hey guys After all I did a couple of weeks back slamming, the pool is slightly cloudy again. I don’t know why? Can anyone help?

Hi there I run my filter 24/7 on low - except for each morning when I schedule to high so my pool heater can work. Someone with a pentair system set up a function called ‘heat demand’ where he runs his filter 24/7 and when the heater clicks on, the filter speed changes to accommodate the flow...

For the past month my SWG is on a higher setting, but not producing the same as it was. It’s still producing chlorine, but previously I would have it on 10% for a FC level of 5. Now I’ve got it on 50 and I can’t get the FC over 4. I don’t have CC. I pulled off the cell and rinsed it - it was...

Ugggh. I just added 40 lbs of salt (heavy rain here in Tampa has meant emptying some water) and turned off the chlorinator in my Omni logic app. The on off switch is flawed in my app so did it 3 times, thought it was off, put salt in and brushed for a few minutes, checked app and it was back...

Hey guys. Just received my Ph meter - thank you. I used it immediately and it tested the same as I tested with the kit this morning. Do I have to do anything special with it? Like use the sachets or distilled water and an absorption pad? Or am I good to go? I’m so relieved to not have to...

Can someone explain why 7.8 is the optimal Ph for getting my CSI to zero? I never go beyond the negative or positive .3 but I’m just interested why this is the case when all manufacturers suggest a must lower number. I keep mine at 7.8 until it moves higher, add MA which knocks it back to 7.6...

I’ve been running my filter 24/7 since opening. I want to change it to running during the day only as we just had solar installed. Can someone help with my schedule please? I need the water to heat in the morning for a couple of hours to get it up to 87 as it drops a bit overnight and have an...

Can I run my pool on low speed (50%) for the entire 24 hours? I’ve been mixing low, medium and high in a 12,200 gallon pool with a variable hayward system capable of 40,000. I have figured out my heater works on low speed as well. Just not sure this would be adequate? 50% speed 24/7. Would...

So I have been following TPF since the day our pool was filled four months ago. Our water is crystal clear and I’ve been pretty pleased with myself. This morning I found some sand on the corner of the bench. And a bit more on one of the ledge loungers chairs. We had a storm last night so I...

Ok so bear with me. I have been mulling over this for weeks and hopefully I can get some answers. I have been diligently testing for salt twice a day for a week. My Hayward system and Taylor’s did not match in fact were out by a few hundred. And while I know that’s ok because I’m producing...

I have a discrepancy between testing Taylor’s and Hayward reading. It’s quiet a large gap, 3300 on Hayward and 2600 with Taylor’s. Leslie’s read it at 2500. It’s producing chlorine. I reached out to PB today and Hayward and waiting to hear back. I’ve asked here a few times about this and...

Has anyone had an issue with claiming warranties after maintaining the TFP levels rather than the manufacturing guidelines? Pebbletec and Hayward suggestions are both vastly different to the levels I am maintaining using this method. Not sure if I should be worried…

Hi I’m not sure what to do. My Hayward t-15 cell is not measuring the same as my Taylor’s test. I’ve done the test repeatedly. Taylor’s is coming in at 2800 while Hayward is telling me I’m at 3265. Should I be worried? Can I fix this discrepancy? If so how? Which is right? And finally...

I added some liquid stabilizer to increase my CYA yesterday - it went from 35-65. I have 80% UV screen on my cage. Is this number for CYA ok? Or should I increase again to get it to 70 minimum. It could be 70 already as it’s hard to tell when that little black dot has actually disappears...

Not sure which Hayward SWG I should choose in the pool math app? Doesn’t anyone know?

Hi I am running a Hayward salt cell system. Pool is 6 weeks old. According to Hayward diagnostics it is sitting at 3415 average salt. It was up at just over 3500 until Sunday when I decided to empty some water. It dropped nicely to 3415. It is producing loads of chlorine - I have it set at...
