How a Pool Pro Controls and Adjusts pH in a Swimming Pool

Rising pH can be frustrating for many pool owners and pool pros. You can add Acid, and the pH will be restored next week. You may be trying to lower it, but nothing is happening. Video Outline: Controlling pH, specifically rising pH, can be a real challenge. Water features add to aeration, which raises the pH. SWG adds to rising pH during their manufacturing process of making chlorine. pH tends to increase in plaster and PebbleTec Pools. New pool plaster has a very high acid demand, and you will find pH rising in a new plaster pool rapidly for the first six months. More stable in Fiberglass and Vinyl Pools. Control the speed of rising pH by using these three buffers: Lower ALK around 70-80 ppm CYA level of 50-80 ppm Borates at 50 ppm Think of it like this: Vegetation buffers reduce overland runoff. New football helmets buffer hits from other players and act as shock absorbers, reducing concussions by at least 75 percent. In the same way, low ALK, a proper CYA level, and borate buffer pH slow their rise in a pool. Turning off water features. Reduce Salt Cell output to below 50%. 3" Trichlor tablets also help keep pH lower since they have a pH of under three. For this reason, limit your 3" Trichlor Tablet use in Vinyl and Fiberglass pools as they lower the pH in those pool surface types. pH below 7.2 can damage equipment, corrode liners, and sting eyes. Use the LSI to see if your pH might be excellent even though it is high. I recommend the Orenda APP for this. Test the pH in your pool. Lower pH with Muriatic Acid 31.45% Dry acid You can install a Co2 tank to lower pH – more for Commercial Use Acid Magic is also effective. To raise pH, add 20 Mule Team Borax. You can also add Soda Ash Baking Soda raises a pool ALK and not pH, so don't use that. Ultimately, "chasing pH" is unnecessary, and shooting for a target pH of 7.5 is a good rule of thumb. But it would help if you also referred to the LSI to see your pool's ideal pH based on ALK, Calcium Hardness, and water Temp, among other factors. Side note (not in the video) using adjusted alkalinity: Adjusted alkalinity is calculated by subtracting one-third of the CYA level from the total alkalinity (TA) reading. For example, if the TA is 120 ppm and the CYA is 75 ppm, the adjusted TA would be 95 ppm. It is also important to note that you may think your pH is high in your pool when it is perfectly fine at 7.8. Based on the LSI, the ideal ranges may not be suitable for your pool. If you haven't studied or used the LSI in pool balancing, there is no more excellent resource than Orenda. Not only can you use their free LSI calculator, but they also offer three free courses that will teach you how pH at a higher level can benefit your pool. Orenda: https://www.orendatech.com/ Many things can cause the pH to rise in your pool. A Saltwater generator produces a byproduct that causes the pH to increase rapidly. Any spa spillway or water feature will cause the pH to rise through aeration. The pool surface in itself can cause the pH to rise. High Alkalinity in the pool can cause the pH to stay high. pH is the most critical test factor for your swimming pool, and if it gets out of balance, you will encounter many adverse effects. Low pH will cause: Corrosive Water Stains Etched plaster Eye & Skin Irritation Cloudy Water Increased Chlorine Activity Destruction of Total Alkalinity Stretching of Vinyl Liners Blistering of Fiberglass Pools High pH will cause: Scale Formation Stains Cloudy Water Short Filter Cleaning Cycles Eye & Skin Irritation Poor Effective Chlorine Testing for pH: Testing once a week is ideal. For a new pool, start-up testing daily for the first two weeks is recommended. However, once a week, you will get a good indication of how stable the pH is in the pool water. There are various ways of testing the pH, such as test strips, basic test kits, and Taylor kits, which use reagents. Alternate testing can be done with the ColorQ Pro7 Photometer and Digital pH testers. Visit my Website: http://www.swimmingpoollearning.com/ eBook: https://www.swimmingpoollearning.com/...
