First off. Thanks for keeping us up to date with Pool Math. It has definitely become an indispensable tool for keeping up my pool. So far the only comment I have on the new look and feel of the app is that I did prefer the old summation page for my android. Otherwise the rest of the new look...

This is my valve I need to adjust. On the far right is the suction coming from the bottom pool drains. It currently is CLOSED for this illustration. The bottom line is the skimmer and where my question arises (has red circles on it). From the current valve position, I can turn the valve...

Just a philosophical question concerning my SWG. Background: Currently increasing the percentage of runtime on my SWG by 5% increases my FC production by 0.2. In other words, if my SWG at 45% is producing FC=1.9, then if I increase my SWG to 50%, my FC production goes up to FC=2.1. The very...

This is a very strange bug so I included screenshots to help out with the explanation. I am using an android phone, Galaxy S22, with Android 5.1 installed. I have three pools entered into PoolMath (Cuzzi Pool, Inground, and Jacuzzi) in the listed order. When I select the Jacuzzi, the last...

Brand new pool with a Hayward T15 SWG and cartridge filters. So after the build when the pool was basically handed over to us to take care of, I asked the Pool Guy, "Why is the pump set to run for 12 hours a day, 6 hours at 50% power and 6 hours at 80% power?" His answer was that that was the...

I have a new inground pool that was being maintained for three months for free by the installer's pool cleaning company. It was always a cringe moment every time the Pool Guy came because I knew he was going to treat my pool for a week and not on a daily basis like TFP. Well it is over and I...

My Hayward VS pump is set to come on and run for 6 hours on 50% power and then 6 hours on 80% power. When the pump first comes on, it goes into prime mode before switching to 50% power. When it originally starts up on 50% power the pump will acquire an approximate 3 inch diameter air bubble...

So typical thunderstorms and torrential rains typically hardly move the scale on my pool's chemicals. However here comes Hurricane Sally with 20 inches of rain in my area and limbs, leaves, and other debris. So what were the results of all of this except for the hours to clean all the debris...

I noticed that most people do not have their pools enclosed in a screen enclosure. I was wondering if there is a reason why you chose not to enclose. What are some of the advantages and disadvantages of having your pool enclosed? I was thinking a huge advantage was preventing critters and...

Just a hypothetical here... During a SLAM, it is typically recommended that you turn off your SWG. If you are a follower of TFP, you most probably purchased an SWG that is twice the size necessary for your pool. Given that if you had to perform a SLAM wouldn't it be beneficial to bring your...

Well when it started getting colder and the pool water dropped into the 60's, my CircuPool SWG started giving strange error messages starting with the word "Temp" and the generator light started blinking. These forums once again came to my aid and quickly identified that the controller error...

I am having a very weird problem with the Chrome browser and my new Surface Pro 7. When bringing the forum up in Chrome only the top half of the screen contains the forum unless I scroll to the bottom of the forum. Once I hit the bottom of the forum and scroll back up towards the top of the...

OK, this is a strange question. I have a new SWG that is connected near the return eye. I also have a PVC fountain that works by replacing the return eye with the fountain. We basically have been using this fountain when the pool gets too hot to help in cooling it down. The SWG produces...

Let me start out by saying, I love the app. But the only complaint that I have is that you must compare your results to the APPs recommended range to determine if your test results are correct. A new feature that I want you to consider is to have the APP highlight a test result that is not...

Reading Pool School, the recommended TA setting is between 60-80 ppm. Matter of fact the exact quote is: "Adjust your Total Alkalinity to 60-80 ppm. (This is IMPORTANT!)" I do have mine currently set at 60 ppm, and my pH has been rock steady at 7.6 for 13 days. My question is why is the...

I am an EXCEL addict and would love to have my test results from Pool Math App to EXCEL so that I can plot them, produce trend lines, etc. Is this a feature being considered? Comma delimited would be great since it would be much easier to implement. BTW... wonderful App! The only criticisms...

According to recommendations for a vinyl pool: FC = 4 pH = 7.5 TA = 70 CYA = 75 Salt = 3200 and CH = 0 <-- don't add You will get a CSI of around -2.89. My question is "Will this do harm to the SWG?" Does CSI matter in a vinyl pool even with a SWG? I have no heater. Only the pump...

I have an aboveground pool that I want to add a CircuPool RJ-45+ SWG . The plumbing is very accessible, and I can place a post in the ground to mount the RJ control box. The problem I am running into is that my pump is a two-stage pump (Pentair Optiflo 1.5hp) that is plugged directly into a...

Almost exactly a year ago, I purchased the CYA Standard from TFTestkits. When I received it, I used it to ensure that I knew what it looked like to get a CYA of 50. It worked great and I was confident in my testing. Today, I was questioning if my pool CYA was 40 or 50, so I brought out the...

I know that Pool School says that CSI is not that important in an UGP. However is there some particular CSI I should shoot for? In other words I have had CSI range from -0.22 to -0.97. Is this bad? When it gets around -0.97 should I add Calcium to raise it above -0.6 or just don't worry...

This is just for my own curiosity, so I thought I would post it here to see what the consensus really is. According to Pool School: However I also here others say that another criteria is: While I have also seen areas where long time users expand the latter to say: So who is correct? Is...

So as I was vacuuming my pool today, I noticed this leaf kind of floating around at the bottom. I attempted to vacuum it but for some reason, it would not come up. So I reached down to grab it when I discovered it was attached! A WEED! had grown up through my liner into the pool! :mad...

Yes, I finally did it. Put away the bottles of Chlorine and filled my little Duck with 6 pucks so that he could swim again. :paddle: Ok, so that is not the entire story. In reality, I have this huge container of pucks that I put away in storage when I discovered this site. I had CYA over 90...

I was checking the Chlorine and discovered that I needed to add more. During the winter, I was adding about 1 gallon of chlorine every couple weeks. Well when it started to warm up, I started having to add chlorine every week, and then recently every two days. Well yesterday I discovered I...

Well I just received my first robot and used it today. What an awesome little guy! He walks up walls, sucks up debris, and is quiet as a mouse. After he is finished (2.5 hours), you just lift him out of the pool, pull out his two sets of filters, and spray them off. Talk about easy. If I...

Bought some of the 10% today. It was dated for mid December, but that is close enough in Winter time. Surprised they already started rolling it out. :)

I just bought the Speed Stir and love it. However how do you guys drain the cylinder and catch the spinner after testing is complete without getting the chemicals all over your hand? I have had to pour the liquid out very slow leaving the spinner in the cylinder. I then fill the cylinder with...

I did a little experiment to see how long I could leave the pool and go on vacation if I brought it to SLAM level before I left. The goal here was to learn the rate the pool dissipated the chlorine so that I would know when I would need someone to come over and add chlorine. With CYA=70, my...

I am a little confused why we have "The Pool Calculator" sticky link at the top of the forum. The standard answer from the long time members has been to use the "PoolMath" link at the top of the page since it is updated and avoid "The Pool Calculator". It just seems confusing to me (and...

When I was running low on reagents, I made a reorder basically to use to refill my bottles in my Taylor test kit. I ordered the 16 oz bottles of the reagents with one exception, the R-8071 reagent. For the R-8071 reagent, I had ordered the 2 oz bottle. I was pleased to find that when the 2oz...
