High Alkalinity

When total alkalinity levels are too high, water problems such as scale build up and cloudy water are likely to occur. As alkalinity acts as a buffer for the pH in your water, high alkalinity levels usually mean high pH levels also. This can cause skin and eye irritation in your bathers and your sanitizer will be less effective.

The way to combat high alkalinity and bring it back into the proper range is to use a pH decreaser such as Spa Pure pH Down or ProTeam Spa pH Decreaser.  Even if you pH is not high this product can be used to lower alkalinity then simply bring ph back up with a pH increasing product.

Low Alkalinity

Alkalinity that has dropped below recommended levels can cause corrosion of metals and equipment in your spa, skin and eye irritation, and rapid changes in your pH levels.

If your alkalinity is low but your pH levels are within the recommended range using Spa Pure Alkalinity Increaser or Proteam Spa Alkalinity Up should return your levels to normal after dosing instructions are followed.

If your pH is also low you will want to use a ph Increase to bring pH up first and then finish off balancing the water with an alkalinity increaser.

As always the best way to maintain balanced water is to test often with a water test kit and make adjustments as needed. Frequent testing and balancing should keep any problems from getting out of hand and causing serious problems in your hot tub.

That is a great question, hot tub scale can be caused by a few different things, hard water, water that is highly alkaline, water with high iron or calcium, and body oils, lotions, and other contaminants introduced into the water by bathers.  No matter the cause of your spa scale build up, there are a few things you can to avoid it.

Steps to Avoid Hot Tub Scale Build Up

1. Use a pre-filter when filling the hot tub. This will help in removing minerals from the water prior to it getting in the hot tub.
2. Make sure you pH, alkalinity, calcium hardness and sanitizer levels are being properly maintained by frequent hot tub water analysis.
3. Use SpaPure Stain and Scale Preventer regularly as it will help break down hard water and minerals, which will prevent build up.
4. Use a Scumball, this little floating ball will absorb body oils and other contaminants brought into the spa by bathers, keeping them inside it instead of them building up on your spa.
5. Make sure you clean your filter regularly; a dirty filter will not be able to pick up as much as a clean one which can allow things to build up causing scum. Cleaning your filter regularly includes rinsing it with your garden hose and then soaking it in a product like Spa Pure Filter Cleaner to get the best clean.

Following the above steps should help prevent hot tub scale build up. If you currently have scale build up that needs to be removed, use either ProTeam Surface Clean or Spa Pure Cleaner to help remove the build up, and get your spa sparkling clean. Once you have removed existing scale, start over with fresh water and follow the steps above to avoid hot tub scale in the future!
