20064 Scaletec Plus Calcium Pool Descaler, Iron and Scum Remover & Preventative, 64. Fl. Oz Bottle

This is a great product. Our inground pool liner was almost totally covered with a white substance and wouldn't brush or vacuum off. It took three weeks and I was informed upfront it would take time a long time but this product save us thousand by buying a new liner. I would buy this product again and again.

I recently used ScaleTec on my fiberglass pool, and I can’t emphasize enough how incredible this product is! It has worked wonders in removing all the scale hardness that had built up over time, and I am absolutely thrilled with the results. From the first application, ScaleTec proved to be highly effective. I followed the instructions and noticed significant improvement within just a few days. The scale that had been clinging stubbornly to the surfaces was dissolved, leaving my pool looking crystal clear and sparkling. It felt like I had a brand-new pool again! Using ScaleTec was straightforward and hassle-free. The product is easy to apply—just add the recommended amount to the water, and it does the work for you. I appreciate that the application process was not time-consuming, allowing me to enjoy my pool rather than spend hours scrubbing away at stubborn scale. As a fiberglass pool owner, I was initially concerned about using a product that might damage the surface. However, ScaleTec is designed specifically for fiberglass and other pool surfaces, so I felt confident using it. After multiple treatments, I can say with certainty that it is safe and effective without causing any harm to my pool. Not only did ScaleTec remove the scale, but it also improved the overall water quality in my pool. The water feels much softer, and I noticed a significant reduction in cloudiness. This product has made maintenance much easier, and I’m confident that my pool chemistry is in great shape. Considering the results I achieved, ScaleTec is an excellent value for the price. It saved me time and effort and has extended the life of my pool’s surfaces. I feel like I invested in the longevity and enjoyment of my pool. If you have a fiberglass pool that is experiencing scale build-up, I highly recommend ScaleTec. It has transformed my pool maintenance routine and restored the beauty of my swimming space. With its ease of use and outstanding results, it has become a must-have product for any pool owner. Say goodbye to unsightly scale and hello to a pristine, inviting pool! You won’t be disappointed!

This stuff helps prevent scale but IME it does not remove it once formed. It is easy to use but needs to be constantly added to the pool. You can swim right away after adding it.

Reading the reviews may lead you to believe this is either a miracle product or completely worthless. I doubt it can fix years of neglect in a single application and I am sure pool and climate differences could effect this product. We have a 39,000 gallon gunite saltwater pool. At year 3 a concrete contractor removed some concrete and in the process tons of the concrete dust settled on the pool surface turning our beautiful pool as rough as a Brillo pad. After a season of trying everything to make it better we added 2 gallons of Easy Care at the beginning of winter. We do not close our pool so the Easy Care circulated all winter and like magic the surface was smooth again. Two years later the pool became rough again like all Gunite pools do and 2 more gallons over the winter make it almost like new again. Now, we just add two gallons at the end of every season. We are in a southern state with extremely hard water. I cannot speak to the issues other people have but we have had great success with EasyCare and find it well worth the money.

I had high hopes of using this product to tackle my severely scaly pool - not just regular scale, but dirty brown scale. Not a pleasant thing to look at. I thought I would have to have an acid wash but was afraid to drain the pool because of the risk of floating it. I had tested the scale with muriatic acid and had no problem removing it. However, due to neglect and low calcium concentration of the water, minerals had been drawn out of my wall and had stained the entire pool - floor and all walls. We're not talking a light stain - but really thick, rough, and ugly absolutely everywhere. Scrubbing alone didn't do a thing and my local pool store recommended ScaleTec. Of course, their prices are much higher than what you pay here. Thus, I ordered twice as much as needed because I wanted to give this product every chance I could give it by having a follow-up roughly 30 days after initial application. I balanced the water before according to directions before adding the product. Then I scrubbed. And I scrubbed. And I scrubbed. I made sure the water stayed within the recommended values and added a second dose of ScaleTec. Then I scrubbed. And scrubbed. And scrubbed. I waited for a long time - but there was absolutely no difference in appearance. In the end, I would not purchase this product again - obviously because it didn't do a thing other than drain money out of my wallet. Perhaps it works well with light scaling, but anything serious can, apparently, not be removed by this problem. If you have some serious scaling, opt for an acid bath - that's what I did. Sealed off my actual pump and filter, dumped quite a few gallons of muriatic acid in the pool to lower the pH to unpleasant levels, agitated the water with a sump pump, scrubbed, and had a mostly scale free pool one week later. There still was serious staining at the deepest part of the pool that brushing in the acidic water did not remove. I re-balanced my water as quickly as I could - pretty easy stuff that didn't take more than three days. For that, I attached a large funnel to some PVC pipe, lowered the end of the pipe to the dark scale, slowly poured muriatic acid into the funnel, and watched the scale disappear before my eyes. Since my pool tends to run high on pH, adding the acid to remove the scale didn't even negatively affect the water.

I did not really see a difference. The product did not make the scale softer nor easy to remove.

My local pool store is no longer carrying this decalcifier. Due to high evaporation of my pool water, I need to breakup the calcium on my pool tiles. This product is the best I have found for the job. Glad Amazon carries it.

Works great. My go to for our salt water pool
