You should remove the scale from the tub as soon as possible to prevent it from returning and damaging the surface. In this article, we’ll talk about how to remove the scale effectively.
CLEAN YOUR FILTER
The filtration system is an integral part of keeping your spa water clean. It’s important to regularly clean it to maintain the quality of the water and remove any impurities.
TEST THE WATER
There are three main contributors to spa scale growth: high pH levels, high alkalinity, and calcium hardness. Getting started with testing your water can help you identify the issue and fix it.
Follow the manufacturer's instructions when using spa balancing chemicals. Be sure to read all the labels and instructions before applying the chemicals.
pH: 7.2-7.6 ppm. Use pH increaser or decreaser.
Total alkalinity: 80-120 ppm. Use alkalinity increaser or decreaser. Some pH adjusters will also alter the alkalinity reading.
Calcium hardness: Spa owners typically fine with calcium levels of 200 ppm to 400 ppm. If they are low, add a calcium booster. If they are high, drain the spa and replace with a filter to remove any excess calcium.
Sanitation: Keep sanitizer levels between 1.5-3 ppm for chlorine and 3-5 ppm for bromine.
BRUSH SPA SURFACES
If you have a steel hot tub, brush gently to remove the excess scale. If you have an acrylic hot tub, use a more gentle brush to avoid damaging the finish.
DRAIN THE HOT TUB
If the scale is severe, then it's time to drain your hot tub. Doing so correctly will remove all the bacteria and dissolved solids from the tub.
A good quality scale preventer is a must have for minimizing the spread of calcium and other stains on your hot tub. This product from Leisure Time is made with organic polymers that can help prevent future stains.
By regularly maintaining your hot tub, you will be able to say "GOODBYE" to it!
