Safety is the top priority, so always handle each product individually and follow the guidance provided on the label for safe and effective use.

What happens if my calcium hardness is too low?

When calcium hardness levels are too low, the water becomes aggressive and seeks to balance itself by pulling calcium from your pool's surfaces. This can lead to the etching of plaster, the erosion of grout, and the corrosion of metal components like heaters and ladders. Over time, this causes significant and costly damage to your pool structure and equipment. By using a calcium hardness increaser to maintain the recommended levels, you protect your pool from these damaging effects. Regular testing and proactive treatment are essential to keep your water balanced and your pool surfaces in good condition for the long term.

What happens if my calcium hardness is too high?

High calcium hardness levels can lead to the formation of scale, which is a white or gray, rough deposit that builds up on your pool walls, tiles, and inside your filtration system. This buildup is not only unsightly but can also restrict water flow, reduce the efficiency of your pump and filter, and create a rough surface that is uncomfortable for swimmers. If levels are excessively high, you may need to partially drain and refill your pool with fresh water to lower the hardness. Always aim to keep your levels within the recommended range to avoid these common and frustrating maintenance issues.

Is this product safe for all pool surface types?

While most calcium hardness increasers are formulated for general use, it is important to check the product label and your pool manufacturer's recommendations.
