Why does my hot tub feel slimy?

• <div><p>Biofilm growth can cause a hot tub to feel slimy. Hot tub biofilm is a slimy substance that’s typically due to natural contaminants like makeup, soaps, skin oils, deodorants, or lotions. A hot tub can also have a slimy interior or slimy water if the tub’s filters are old or damaged, or if the hot tub isn’t properly cleaned. You should drain your hot tub, wipe away any slimy residue, then refill the water and use a spa purge product that prevents the buildup of biofilm. </p></div>

Can I raise the alkalinity in my hot tub?

• <div><p>Yes. If you test the water and the alkalinity is too low, you can raise it by adding an alkalinity increaser, which likely came with your hot tub’s chemical kit. In a pinch, you can use baking soda to raise the hot tub’s alkalinity. Raising the alkalinity will prevent the hot tub water from becoming too acidic.</p></div>

Q: What happens if I don’t clean my hot tub filters?

• <div><p>If you don&rsquo;t clean your hot tub filters, they&rsquo;ll build up dirt and grime, preventing them from filtering out contaminants like dirt and bacteria. The dirty water will then circulate through the filter and back into the hot tub, leading to dirty water, a damaged pump and jets, and low heat. This can lead to higher <a href="https://www.angi.com/articles/how-much-does-hot-tub-cost.htm">hot tub costs</a> because you may have to pay for repairs.</p></div>

Q: Is it more expensive to repair or replace a hot tub?

• <div><p><a href="https://www.angi.com/articles/hot-tub-repair-cost.htm">Hot tub repair costs</a> are less expensive than purchasing a new one, especially if your warranty is still intact. You can shop for a secondhand unit or find a deal for a trade-in. If the price to repair your hot tub is higher than the cost of a new one, consider replacing your unit. </p></div>

Q: What should you not put in a jetted tub?

• <div><p>Using bubble bath, bath oils, bath salts, or moisturizing products that contain butters or oils can damage your jetted tub. Because of the water pump and jet mechanism, you need to be more selective with products for a jetted tub than you would for a traditional bathtub in order to keep it functioning properly and avoid expensive repairs. These products also leave residue that can feed mildew and mold, so it&rsquo;s best to avoid them.</p></div>

"Rather than fix the issue the first 2 calls, more refrigerant was pumped into the system. This cost me $75 for each call plus the cost of the refrigerant. The 3rd time, they fixed a valve and refilled the refrigerant and I am monitoring to see if this really fixed the problem. So I am out $225 for service calls fro the same problem and the cost of the refrigerant. I think they take this approach intentionally."
