I put too much metal out in my pool by Doheny's my pool is only 10,000 gallons what should I do? Hi David, you need to dilute the water.Drain some, add fresh. Rob Hampton (author) from Port Richey, Florida on June 13, 2019: Keep in mind that it doesn't take much soda ash to increase pH. Once the alkalinity is within the desired range, you will use pH increaser (soda ash) to bring the pH back up without raising the alkalinity. The answer is to use both muriatic acid along with sodium CARBONATE also known as soda ash (Do not confuse with sodium BI-carbonate which raises alkalinity) Depending on how high the alkalinity is, add the desired amount of muriatic acid and let circulate for several hours. The alkalinity can be lowered using muriatic acid with the problem being that it also lowers the pH at the same time. Because alkalinity tends to be a buffer for the pH, it's rare that I see high alkalinity and low to normal pH although it CAN happen. Question: What do I do when my pool pH is good and the alkalinity is high?Īnswer: The alkalinity in pool water should be no higher than 120. This will NOT harm the vinyl liner although unbalanced chemicals over time will have damaging effects. If you are adjusting the pH in a vinyl-lined pool using muriatic acid, add slowly to the deepest part of the pool with the pump on and water circulating. Muriatic acid is commonly used, but also dry acid. Question: Can I add muriatic acid to a pool that has a liner over the cement? Will it affect the liner or melt it at all?Īnswer: All pools need to have pH adjusted. Try this chemical dosage calculator to adjust chemicals.Īnswer: Sodium bi-carbonate (baking soda) will raise the alkalinity. If all else fails, drain the pool and re-fill. If the pump/filtration system is not set up to vacuum to waste or "backwash," other options would be to keep the pH around 7.2, elevate the chlorine and filter out the algae cleaning the filter frequently. After this is done, the water chemistry can then be re-balanced. Some water will be lost during this process. It will need to be then vacuumed to waste (this is sometimes difficult to accomplish with above ground pools). I would suggest brushing the pool and adding a floccing agent such as "Drop-Out" or "Drop-Down" which will sink all algae to the bottom of the pool. Also be sure that the test kit being used is giving accurate readings. What should I do?Īnswer: If the pH is still 8.4 after adding a gallon of acid, there is a more severe chemistry issue. It is still green, and the pH is still at 8.4. I have used a gallon of muriatic acid and shocked the pool.

Once you get the hang of it, balancing your pool and spa water is easy. It’s that simple! Calculations include: Salt, pH, Total Alkalinity, Cyanuric Acid, Total Hardness and Phosphate levels. It makes managing your pool water- fool- proof and incredibly easy.Īll you need to do is simply slide the bar to tell the calculator your pool size and current chemistry levels, and it tells you what to add to your water to bring it into balance. Our easy-to-use online calculator is based on the requirements and recommended levels of The Center for Disease Control (CDC), The Association of Pool & Spa Professionals (APSP) and the National Swimming Pool Foundation (NSPF).
If you do, it makes it far more difficult, time consuming and costly to bring your water back to balance. The key to maintaining healthy water is to keep on top of it, and not let your levels get too far out of range. You don’t have to be a chemist to balance your pool and spa water.
