WHY IS MY POOL WATER “HARD” AND WHY DOES IT GET “HARDER”?

• Hard water in a pool refers to high levels of calcium and magnesium in the water, which can increase over time due to evaporation and the introduction of new water. This can make it difficult for chemicals to effectively sanitize the pool, and can also lead to buildup on the interior finish, tile, plumbing, and equipment.

HOW IS HARD WATER TYPICALLY ADDRESSED?

• The traditional method is to drain the pool, but this wastes a significant amount of water. Using a filtration system to lower the levels of calcium and magnesium is a more effective and sustainable solution.

ARE THERE CHEMICALS THAT I COULD USE TO ADDRESS THIS WATER HARDNESS?

• While there are products that can hold the hardness minerals in suspension, they will not lower the level of hardness. The only true solution is to filter the water and bring the levels down to the acceptable range.

I CAN’T SEE THE HARDNESS IN MY POOL; HOW DO YOU KNOW IT’S REALLY THERE?

• Hard water may not be visible in the water, but it can be seen and felt in other areas such as buildup on spa walls, discoloration on tile, and dry or itchy skin after swimming.

WHAT OTHER PROBLEMS COULD OCCUR WITH HARD WATER?

• Hard water can lead to issues with heaters and pumps, as well as difficulties in eliminating algae and discoloration on plaster. It can also deposit itself in plumbing lines and filters.
