Chemical Balance

When testing and adjusting spa water,you have two types of testing methods to choose from:

Reagent-Kit

The Reagent Test Kit:

is a method which provides a high level of accuracy. It is available in either liquid or tablet form.

Test-Strip

Test strips:

are a convenient testing method commonly used by spa owners.

TA Scale

Balancing the Total Alkalinity

Total alkalinity (TA) is the measure of the total levels of carbonates, bicarbonates, hydroxides, and other alkaline substances in the water. TA can be considered a “pH buffer”. It is the measure of the ability of the water to resist changes in pH level.

The recommended total alkalinity is 80 – 120 ppm.

If the TA is too low, the pH level will fluctuate widely from high to low. Low TA can be corrected by adding an alkalinity increaser.

If the TA is too high, the pH level will tend to be too high and may be difficult to bring down. High TA can be corrected by adding an alkalinity decreaser.

When the TA is balanced, it normally remains stable, although adding water with high or low alkalinity will raise or lower the TA level.

CH Scale

Balancing the Calcium Hardness

Calcium hardness (CH) is a measure of the total amount of dissolved calcium in the water. Calcium helps control the corrosive nature of the spa’s water and is why soft water is not recommended. The low calcium content of soft water is very corrosive to the equipment and can cause staining of the spa shell.

The recommended calcium hardness is 150 – 200 ppm.

If the CH is too low, add a calcium hardness increaser.

If the CH is too high, dilute the spa water with soft water.

When the CH is balanced, it normally remains stable, although adding soft water or very hard water will raise or lower the CH level.

pH Scale

Balancing the pH

The pH level is the measure of the balance between acidity and alkalinity.

The recommended pH level is 7.2 to 7.6.

If the pH is too low, it can cause corrosion of metal fixtures and the heating element. Low pH can be corrected by adding a pH increaser.

If the pH is too high, it can cause scaling by allowing metals or minerals to form deposits and stain spa surfaces. High pH can be corrected by adding a pH decreaser.

When the CH is balanced, it normally remains stable, although adding soft water or very hard water will raise or lower the CH level.

Everything You Need to Know About Keeping Your Spa Water Fresh

Do you want to protect your investment into your brand new spa? A couple simple steps on a set schedule can keep your investment lasting long, looking good, and keep you feeling relaxed with every use. The Basics (Routine Maintenance) There are a couple simple things to keep an eye on in order to keep your spa optimal for regular use. First off, the most important thing is to use your basic senses. Does your water look clear? Does it smell funny? Does the water feel clean? If you notice anything out of the ordinary about your water, you may need to stay on top of your routine maintenance for your spa. If you notice any leaves or large debris in your water, use a skimmer to scoop up anything you can see. If you notice any smells or scale floating in the water, continue in the article to find out how to remedy these issues. A good thing to regularly check is water chemistry. This is one of the most important things to keep track of when maintaining your spa. A couple test strips or pH test kit are a must have to make sure that your spa water is healthy. The ideal pH balance of your spa should be hovering around the 7.2-7.8 range. Any lower and your water is too acidic. Any higher and your water is too alkaline/basic. It is important to regularly check pH because any imbalance can hinder the sanitizing agents and promote bacterial growth or cause cloudy or scale buildup in the water. The chemicals needed are pretty straightforward. If your water is too acidic, add an alkalinity increasing agent to lower the pH, and if your water is too alkaline/basic add proper acid agents to raise the pH. Quickspaparts.com offers all the chemical test equipment you need! Chlorine Test Strips Bromine Test Strips Filter Cleaning (Once every two weeks) Once your pH balances are in check, but you are still noticing issues with your water flow and filter efficiency, it may be time to take a look at your filter. A good rule of thumb is to remove and clean your filter bi-weekly to ensure minimal blockages and maximize the life of your filter. A simple cleaning can be done with a soft brush and hose to dig out any large particles and clear the filter for better flow. Filter Deep Clean (~3 Months) A deep filter clean is great to pair with a routine water replacement for your spa. Quarterly, you should drain and refill the water in your hot tub. While you do this it is a good idea to do a thorough cleaning of your filter. Instead of just rinsing the filter out with water, we recommend soaking the filter overnight in cleaning agents to maximize filter health. Always be sure to do a final water rinse and dry of the filter before re-installation. Replacement (Annually) With regular spa use, it is recommended to do a full filter replacement annually. After regular cleaning, the filter media beings to break down over time. Annually a full replacement is recommended to ensure a long life for all other parts of the spa. Nothing can substitute a brand new filter, and it will feel as if your spa has been completely revived. The water will be cleaner and will flow better overall.
