Attached are my pool math readings for the past five days. I added 31%muriatic acid a day before the first reading in the attachment. My ta is between 50 & 60 which you all say to round up. I will be closing the pool relatively soon so I want to get the chemicals fully balanced. I want to...

I accidentally got the salt level to 3500 - 3600. It is for a t-15 Hayward. Can I leave it there or must I lower the water level to get it below 3400? And early today I added a 40 lb bag of salt. When adding small amounts like that it is recommended to turn off SWG for the next 24 hours...

What is needed to close the pool? Should I buy a kit from Inyo pools?

I believe I’m getting algae in the pool. This is because I have black dots on the steps . When I rub them they turn greenish. And a hint of green algae on the downslope of the liner above the skimmer . Otherwise the water is crystal clear. See attached pictures of the two algae areas mentioned...

Is there any downside to attempting to keep the fc level at the highest amount listed by pool math . My CYA has been running at around 80. Based on that my fc target is 4 to 11. I have been keeping it between 10 & 11.5. See my test logs in pool math - they should be assessable. If I do...

My SWG is about 6 weeks old. From the beginning My test results using Taylor kit have been very close to the Hayward t-15 control box readings. Starting a day or two ago the Hayward began reading higher than my tests. Hayward reads 3200 . I confirmed with a diagnostic instant reading ( of...

I just purchased a Dolphin active 40. It constantly gets stuck on the main drain cover. I tried tuning off the pump for the main drain which helped somewhat. I purchased the zodiac unibridge main drain cover (on Amazon $76). I tried it with no modifications. The dolphin had some success but...

I have an automatic chlorinator which I now will not use anymore unless I’m away . This so I don’t increase CYA levels with stabilized tabs. My question is - is there a automatic chlorinator or method that used liquid chlorine?

Is is safe to add liquid chlorine per pool math calculator ten minutes after adding liquid conditioner?

I have had problems with what seems to be metals all season. I tried many different things before I found TFP. It became so bad mid July I removed about 11000 to 12000 gallons. But today as I’m lowering the water to lower my cya from 80 I notice brown staining on my steps. So I believe I...

I added a signature to my profile in my account. I must have done something wrong because it does not show up when I make a post?

I just signed up for premium subscription to pool math. How can I print out the results along with the suggested chemical additions. I could only seem to email the chemical readings but not the chemicals to add. I have been posting my k-2006 results into Leslie’s app. And then print out...
