How to Adjust Calcium Hardness Levels in a Swimming Pool
When calcium hardness levels become too low or too high, they need to be adjusted to maintain an ideal balance for your pool.There are two primary methods for adjusting calcium hardness levels in a swimming pool: adding calcium chloride or calcium carbonate. Adding calcium chloride is the simplest way to increase the calcium hardness level in a swimming pool. It is available in granular and liquid forms, and it is added directly to the pool water. The amount of calcium chloride needed will depend on the size of the pool, but as a general rule of thumb, add 1 lb for every 10,000 gallons of water.
If the calcium hardness levels are still too low after adding calcium chloride, the pool may require additional treatments with a calcium-based chemical. Calcium carbonate can also be used to raise the calcium hardness level. It is available in powder form and is added directly to the pool water. The amount of calcium carbonate needed will depend on the size of the pool, but as a general rule of thumb, add 1 lb for every 10,000 gallons of water. If the calcium hardness levels are still too low after adding calcium carbonate, additional treatments with a calcium-based chemical may be necessary. If calcium hardness levels become too high, they can be lowered by using a phosphate remover or an acid-based chemical such as muriatic acid.
Phosphate removers are available in liquid and granular forms and should be added directly to the pool water. Muriatic acid is a stronger acid-based chemical, and it should be added cautiously and in small amounts to avoid over-treatment. The amount of phosphate remover or muriatic acid needed to lower calcium hardness levels will depend on the size of the pool, but as a general rule of thumb, add 1 gallon for every 10,000 gallons of water. It is important to keep in mind that adding chemicals to your swimming pool can have unexpected side effects, so it is best to consult a professional if you are unsure about how to adjust calcium hardness levels. Additionally, it is essential to test your pool water regularly and follow all safety guidelines when handling chemicals.
