Following are the basic formulas and calculations to determine surface areas: Area of a square or rectangle: A = L x W Area of a right triangle: A = (L x W)/2 Area of a circle: A = Pi x r x r Calculating Volume Then using the chart below, take the factors and add them together. Are you testing for a spa or a pool? You may also use pea gravel as a base for fiberglass pools. Read on as we answer the most common muriatic acid pool questions. It's very important to include it for an accurate LSI calculation. To lower CH you replace of the water with new water, with CH of. Adding This will give you the square footage of the L-shaped pool's surface area. L-Shaped Pool Surface Area = (Length 1 x Width 1) + (Length 2 x Width 2). These compounds are a side effect of water that is too high on the CSI scale. If you do not have a TDS meter, you can estimate TDS by adding salt + calcium + total alkalinity + CYA. Please check your entries and try again. Contact Us. Dont hesitate to reach out if you have any questions about calcium hardness. This index is important because it incorporates all five of the balance factors into its number; pH, total alkalinity, calcium hardness, temperature, and total dissolved solids.
