3 Causes Of High Alkalinity In Pools

Posted on: 4 December 2015

Few things beat the luxury of enjoying a warm summer day by a nice cool pool located right in your own backyard. But it's not long until the bills come in and problems arise that the full impact of a pool is realized, both good and bad. Not only must you keep track of not only the hardness of the water or the minerals in it, you must always check the pH balance and the total alkalinity, also known as TA. Keeping the TA in check will keep your pH balanced.

Pools require a pH balance of a neutral 7.0. If your pool's pH balance is close to this level, then taking care of TA is your first priority, as high alkaline water is the perfect breeding ground for algae and can also lead to calcium build up. This is what leaves the hard, white buildup around the inside. High alkaline water is also referred to as "hard water." The easiest way to spot that your alkaline levels are too high is cloudy water.

Too many chemicals - Obviously, one of the most common issues with a pool's pH balance is human error. You may live in an area with acid rain without realizing. This will keep you adding alkaline boosters, eventually leading to an abnormal pH. Add the boosters in increments to prevent a sudden change in pH. Checking your pH often is a great way to check the acidity of your rain and keeping the alkalinity at bay.

Sweat and lotion - Of course, there are many chemicals in the lotions and soaps we use on a daily basis. So it's no surprise this contributes to the alkalinity levels rising. Your body may also naturally produce more acids, which are excreted from the body through sweat. This is why your pool may get and stay cloudy after a party with sweaty children slathered in sunblock.

Municipal water source - Often times, municipal water companies will use water with a higher alkalinity to prevent the corrosion of pipes. This is obviously an issue if not checked properly. You may be adding water to the pool that is sabotaging your pH balance without actually knowing you're doing so.

While there may be other causes for the high alkalinity, these are definitely the most common issues for pool owners. Hopefully, finding the root of the problem will allow you an easier pool-owning experience, giving you the opportunity to fully enjoy your investment.
