Hot tub feels like sand paper how do you get rid of this?

Answer 1

I had this problem just about how you explained it. I'm going to make an assumption here and that the 'sand' is sticking to the surface below the water line. The 'sand' can be rubbed off with hard pressure, either with your hand or a 3M pad. The color is white and has the feel of grains of salt. I checked my PH and it was normal. I checked Total Alkalinity and it was normal. If the above is not normal then you need to get it into normal ranges. I talked to my hot tub dealer and explained to him that PH and TA were normal, that it has never happened to me in 20 years. His answer was that the source water was the culprit. The source water for some reason had a high level of calcium and it condensed out of the water onto the surface. His suggested that I add 1/8th of a cup of Stain and Scale control per 100 gallons of water. Wait 24 hours and add the same. After another 24 hours get into the tub and remove the 'sand'. I used a large 3M pad. Run your jets for a couple of hours. Clean the filters. The water will probably be a little cloudy, but just keep running the jets until it cleans up. Once a week add the recommended amount of Stain and Scale control. I hope the next time I fill the tub this won't happen!

Answer 2

To address a rough texture in your hot tub, you can try adjusting the pH and alkalinity levels of the water, as high levels can cause water to feel abrasive. Additionally, consider cleaning and scrubbing the surface of the hot tub to remove any built-up residue or deposits that may be causing the rough texture. Lastly, ensure the filter is clean and working properly to help maintain water clarity and cleanliness.
