Knowing when to collect a water sample can be challenging. It’s important to get the sample at the right time as the water quality can vary greatly based on the time of day and location. The best time to collect a pool water sample is usually early in the morning, while the water is still fresh and clear of debris. This article will tell you exactly when to collect a pool water sample and the best place to do it. Keep reading for more information.
The Morning Is Best
The first thing you need to do is check the water temperature. Most pools are best serviced between 68-77 degrees Fahrenheit. Any variation from these numbers can be an indication that something is wrong. For example, if the water is too warm, it can mean that there’s dirt or chemicals in the pool that are heating up the water. The opposite is also true, if the water is too cold then it can mean that there is algae growing in the pool or nearby area which is causing the drop in the water temperature. Checking the pH of the pool water is also a good idea, as alkalinity (low pH) contributes to algae growth. Testing for hardness is another great way to judge the overall quality of the water in your pool, as hard water can make for great swimming conditions but also causes corrosion on metal pool structures over time. Testing the PH, temperature, and hardness of the pool water all help to form a good perception of the quality of the water in your pool.
When it comes to pool water testing, it’s important to keep in mind some general guidelines. First, only test the water once every quarter or once per month at the very least. Checking the PH, hardness, and temperature too frequently can cause stress on the animals and humans that live in your community because the water sample may not accurately reflect the overall quality of the water at the time of testing. For instance, if you test the water and it comes back with a high PH, this could mean that the pool is getting a little bit more acidic than usual. This is bad if you’re planning on having children around the pool or if you have pets that are prone to urinary tract infections because there’s too much chlorine in the water. In this case, you might want to adjust the PH a bit by adding some alkaline crystals to the water or changing the chemical balance in the pool by replacing some of the chlorine with either bromine or a salt mixture.
The Afternoon And Early Evening
As we mentioned above, early morning is the best time to collect a pool water sample, however, this is sometimes challenging to do because, after all, you have to wake up early in the morning to be able to beat the heat of the day. One great way to accomplish this is to draw the water from an outside faucet and let it settle for a few minutes before testing it. This way, you’re ensuring that you’re getting a clean sample and the water still has the freshness of being pulled directly from the faucet. Remember, the morning is the best time because the water is still cool when sampled, however, the afternoon and early evening are also good times to sample the water as long as you do it carefully. The reason behind this is that the water is still cool when sampled, but after being in the heat a few hours the quality can dramatically decrease.
When testing the water in the afternoon and evening, you must be careful not to contaminate the sample with any chemical additions or change in pH since this can cause inaccuracies in the results. For example, if the pH is low in the afternoon, this could mean that there is either CO2, or acid in the pool that is lowering the pH. There are several chemicals that can be used to raise the pH of the pool water, but again, it’s important to keep in mind the possible effects on the overall health of your pool and its inhabitants.
Late Evening To Early Morning
Once the sun starts going down, the temperature of the pool water starts rising and so does the amount of debris in the water. This is why we recommended earlier that you not sample the pool water in the late evening, as you could potentially collect some dirt or debris along with the sample. The best time to sample the pool water after this point is usually between midnight and 6 am, as this is when the temperature of the water is at its lowest and the debris has not yet started to accumulate on the bottom of the pool or around the pool area.
Even if you have the most ideal pool for a swimmer, there will always be times where it’s not going to be in the perfect condition. This is why it’s important to test the water regularly and know how to deal with issues as they arise. Knowing how to collect a pool water sample and what to look for can help you determine the quality and condition of the water all season long, no matter what. It might be a little tricky to get the sample in the morning, but it’s worth it.
