Things that Will Affect Pool Water Chemistry

In those hot summer months, when sweat rolls down your neck, a pool can be a huge benefit. A swimming pool has the power to lower your overall temperature, give you a place to relax and think, as well as an area to play or splash around. There are many positive aspects to owning your own swimming pool, such as your ability to throw pool parties, tan for free, and even use the pool as your only mode of exercise. As there are many uses for a pool, there are also many factors to keep it functional. After all, pools rely on the combination of clean water, circulation, and chemicals to remain safe and useful.

Chemicals are a large factor in swimming pool maintenance. Without the proper chemicals, your pool would become dirty and algae infested. However, it takes a real alchemist to know how much of each chemical to place in the pool to regulate appropriate amounts of chemicals. If there is a chemical imbalance, you could subject your body, as well as your pool, to either too harsh or too light of chemical mixture. In this blog, we will discuss the different factors that can throw-off your pool water chemical balance. Because some of these factors cannot be helped, it is almost impossible to maintain regular water chemistry all of the time. However, by noticing how these factors can affect the quality of your pool water, perhaps you will take measures to either protect against complete water-content imbalances.


Rainwater is acidic. In fact, due to its lower pH number, it can actually adjust the acidity of your pool water. Pool water should never have a pH level lower than 7.2. Because rainwater can throw off the pH balance so significantly, it is always a good idea to cover your pool with some sort of cover. Rain cannot be helped, which is why the only thing you really can do is provide a cover and call a pool service to help regain pH balance after the storm
If you do not treat your pool after a heavy rain store, three things could happen:

  1. The water in your pool will become diluted and corrode your pool services and equipment.
  2. The low pH level will make your pool uncomfortable to swim in and the chlorine in the water will evaporate quickly.
  3. Because of the imbalance, your pool could have an algae outbreak, which will make the water cloudy.

All of the above options are not desirable for your pool. After all, the idea of having a pool is to use it as much as you can. If your pool is cloudy, uncomfortable to swim in, and corrosive, you won’t be able to use it as often.

Pets and People

Pool chemical maintenance is no simple task. You have to have a complete understanding of chemicals, pH balance, and what factors react poorly to your pool chemicals. Remarkably, one of the main damaging factors to a pool’s chemical balance are swimmers and their pets. When you step into a pool you have to assume that anything on your body will naturally mix into the water, this includes; your shampoo and conditioner, lotions, sunblock, perfumes, and anything else you put on your body. It has been found, that the average woman places over 515 synthetic chemicals on her body. Because of this, foreign chemicals are added to your pool which can adjust your chemical balance. So, in theory, it is best to shower before you jump into your pool. The issue with this is that if you shower, your sunblock will come off, which will leave you horribly burnt by the end of the day. One of the best ways to use your pool is to take a preliminary shower to wash off any excess chemicals off your body. You should then pat yourself dry and then apply sunblock. Make sure that you are entirely dry before you put on the sunscreen, otherwise, the location will not soak into your skin and be useless.

Pets can also be a significant problem for pools because of their flea and tick treatments. Due to the added chemicals in dog treatments, as well as the shampoo you use on your pet’s coat, the added chemicals could be problematic for the chemical balance of your pool.

Other Chemicals

Calcium hardness is a fundamental factor in the chemical maintenance of your pool. Calcium is needed to determine the hardness of the pool. Yes, pool water can vary in softness and hardness, believe it or not. Calcium is used to clear the water so it does not become clouded or algae infested. Too much calcium in a pool will lead to bonds with carbonates and form calcium carbonate compounds. This will result in rough or “hard” water surfaces, clouded water, and a less effective circulation of water through your filtration system.


Circulation is extremely important for pool health. Without circulation, your pool will be nothing more than a large backyard pond. Things like algae thrive in environments with stagnant water. If your pool does not have proper circulation, algae will grow quickly and ruin the quality of your pool water. This can be dangerous because algae can be highly infectious. In order to keep your pool water healthy and clean, it is recommended that you circulate your pool for about 10 hours.

Circulating the water also is healthy for your pool’s water because it will ensure that every inch of your pool is mixing with the right amount of chemicals.

Debris and Leaves

Leaves and debris will naturally harm your pool. Anything, from leaves to branches, can be bad for the health of your pool. For one, debris can introduce bits of dirt into your pool which can make it filthy. Second, leaves and other bits of materials can add up and cause blockages in your pool filtration system.
The best way to ensure that debris and leaves stay out of your pool is by investing in a quality pool cover. And, during the times that your pool is uncovered, you should always have a pool cleaning net at the ready.
