The precise point at which CO is in equilibrium with CO above the water is known as pH(eq), or as we at Orenda call it, the pH ceiling. It should be on the lower end of that spectrum for vinyl liner and fiberglass pools (200-250), and the higher end for concrete pools. We recommend shocking with either Calcium Hypochlorite (un-stabalized granular only, not tablets) or with Liquid Chlorine (Sodium Hypochlorite). These numbers are only suggestive of the relative magnitude of the pH change you can expect. The Relationship Between pH and Total Alkalinity. Read more about the Calcium Saturation Index here. A chemical engineer by trade, Louis is committed to debunking myths in the pool industry by explaining the underlying chemistry and making it accessible to all. washing soda or soda ash If the depth varies, use the average depth of the pool. The present industry standard for calcium hardness is from 200400 ppm in swimming pools and 150250 ppm in hot tubs. To do this, add the shallow-end depth with the deep-end depth, and then divide this by two. Having a free chlorine reading of zero means that all of the chlorine is being used and that the amount that you are adding is not enough to clean the water. In most cases, raising pH with soda ash is unnecessary because pH naturally rises due to CO loss. One side would often have a longer width than the other. calculated pool volume. These compounds are a side effect of water that is too high on the CSI scale. To work out how much calcium increaser to add to your pool, you need to do the following calculation: Calcium Dose = Pool Volume x (Target Calcium - Current Calcium) For a 60,000 L pool with current calcium of 150 ppm and a target calcium of 250 ppm, the calculation looks like this: Calcium Dose = 60,000 L x (250 ppm - 150 ppm) You may also use pea gravel as a base for fiberglass pools. Water Testing 101. The present industry standard for calcium hardness is from 200-400 ppm in swimming pools and 150-250 ppm in hot tubs.

If your pool's pH level is too high, you can lower it by adding muriatic acid (hydrochloric acid) or sodium bisulfate). About this app. Using feet as the unit of measurement, the formula for the volume of an L-shape with a sloping deep-end is: L-Shape Volume = (Length 1 x Width 1 x Average Depth) + (Length 2 x Width 2 x Shallow End Depth). It's very important to include it for an accurate LSI calculation. Pool Volume Calculator. For weight, its measured in ounces. This pool calculator assumes that the smaller part of the L-shape is shallow water, while the larger part of the L-shape slopes down to the deep-end. Like CYA, borates contribute to Total Alkalinity (TA), and therefore must also be deducted when calculating the water's carbonate alkalinity (or corrected alkalinity), which is required for the LSI equation. Reduce alkalinity over several treatments with diluted acid. Total alkalinity stabilizes pH levels. Calcium hardness is needed to balance your pool's total alkalinity.
