Problems with Old Pool and Hot Tub Water

Old water can pose a problem for both the swimmers and the hot tub. Swimming pools and hot tubs are used by thousands of swimmers every year. This means that foreign contaminants can be introduced to the water. Your water may not be safe from detergents or other cleaning chemicals. Swimmers can also bring soaps and oils to your pool. These swimmers also sweat and expel saliva as they exercise or play in the water. You might be surprised to learn that some swimmers can leave behind fecal remains if they haven’t washed their feet before entering your pool. Yes, swimmers can bring poop to your pool!

In addition to what swimmers bring, contaminants can also be brought into your hot tub or pool by the surrounding environment. Your pool can be infected by pollen, dust, debris, animal feces and other chemicals. These are only a few foreign entities that could find their way into your hot tub or pool.

All of our chemicals for swimming pools, from Chlorine to Sodium Bicarbonate, will dissolve completely in the water. However, a small amount of them will remain in your water. This is what the industry calls total dissolved solids.

What are Total Dissolved Solids, and How Do They Work?

It is easy to understand total dissolved solids. This is the measure of everything in your hot tub or pool that dissolves in the water and shrinks to a size we can’t see with our naked eyes. The main problem is TDS (total dissolved solids), which are difficult to see. TDS (total dissolved solids) is invisible. Algae can be seen, and stains can be seen and removed. TDS, however, is your invisibility. TDS is also heavy. TDS is not carried with water when it evaporates from the pool. Instead, the water evaporates, and the TDS builds up inside the pool.

Are Total Dissolved solids bad?

TDS can be very harmful to your hot tub or pool. TDS can cause galvanic corrosion in your hot tub, leading to discoloration. TDS can cause your water to become dull, hazy and lifeless if it is too high. To keep your hot tub or pool water clean and clear, you must remove the TDS from the water.

How can I get rid of total dissolved solids in my hot tub or pool?

The only way to eliminate all dissolved solids from your hot tub or swimming pool is to drain them. There is no way to reduce your TDS levels. Adding more chemicals will only increase your TDS. Although it may not be ideal, fresh water is the only way to ensure that your hot tub or pool is clean. Now that you know what TDS means and how it is removed let us explore how to drain your hot tub or pool.

How Often Do I Need to Drain My Pool?

There is a simple answer to when you should drain your pool. After filling the pool with water, take out a TDS meter to measure the TDS. This is your starting TDS reading. Keep testing your water every two weeks, and note any rises in TDS. When the TDS levels rise to 1,000 ppm above the initial TDS reading, it’s time to drain the pool and refill. This will occur more quickly in certain pools than in others. I recommend that you not use any of the hackneyed formulas found online or in books, as they do not address your pool’s user loads.

How often should I drain my hot tub?

It is similar to draining your swimming pool. When the hot tub is empty, you will take the initial TDS reading. You’ll then monitor the TDS levels of the hot tub until it reaches 1,500ppm. The TDS in a hot tub will rise faster than in a pool. This is because hot tubs are smaller and have more people in them at once.

How do I drain my hot tub or pool water?

Follow the EPA’s guidelines and your local codes regarding where the hot tub or pool water can be drained. It is safer to drain the treated water through the waste hole in your pump room with a sump pump.
