How to Control Calcium Hardness
Maintaining appropriate levels of calcium hardness is a key balance factor in basic recreational water care. Typically, water in a vinyl-lined or fibreglass swimming pool should contain a calcium hardness level of 175 to 225 parts per million (ppm), while the recommended range for plaster-surfaced pools is a little higher at 200 to 275 ppm. In addition, the overall balance … Read More
Battling Biofilm in Pools and Spas
Improving water quality demands a true understanding of what is hidden in the pool and spa environment, of what is lurking beneath the surface—in piping, filters and on exteriors.
