We were loosing about 3” of water per day, if not more, following a process of elimination I checked and renewed all the above ground pipework, fittings and filter, we have a new pump so we knew this was also leak free. Ou pool is set in to a concrete pad so I wasn’t looking forward to breaking the surrounding area to search for a leak, so in a last effort to find a solution and after some research and found this, I have to admit I was skeptical about this actually working, I followed the instruction carefully to the letter, then with some patience to let the product settle and cure for a few days it has worked amazingly. We are on day 5 of hot weather with the pumps running only at night and the water level has not moved at all. Great product. Review: The Real Deal! - I followed directions to the T and...@#%*! THIS STUFF WORKS!! As a repair tech I'm well familiar with "stop leak" products used in many industries. Some work better than others and exact circumstances can make all hit or miss. I was actually pretty skeptical about the ability of a working solution (punintended) to fix my good ol' 4-person hot tub, the victim of a winter power failure that caused freezing in the water lines. That would be a fatal condition for most tubs, but NOT the hard-won "portable" tub that I vowed I would never try moving again in my lifetime. Not that there's all that much of that remaining, but all the more motivation to bring my beloved "Think Tub" back to life. So, after rebuilding the heater (too old and costly to replace) and replacing the pump, it was with INDESCRIBABLE sadness I discovered the tub was leaking water from points unknown at rate that would make it more suited as a planter. My indefatigable nature--exacerbated by $200 repairs already expended--led me to Fix-a-Leak. Reviews were surprisingly positive, but even if it wasn't snake oil I didn't have much confidence it would work for my potentially sieve-like tub. After some reflection I decided I could spring for another $22 before crying "uncle!" May well have turned out to be the best $22 I've ever spent! It took me 3 months to garner enough courage and emotional fortitude (oh, and time) to carry out the steps required to check the stuff out. Had I opened the bottle immediately I may have been encouraged enough to try sooner, when the weather was more conducive to the company's online "warm weather" instructions. No matter, they provide instructions for freezing weather as well and those are the ones I followed. Admittedly between those instructions and the actual liquid characteristics I was encouraged. It made sense. The solution is viscous enough, and obviously contains particulates, probably rubberized, that, when well-suspended in the tub water, could coagulate at the leak points and, eventually, HOPEFULLY build up to the point of flow stoppage. In my case, THOSE LITTLE BUGGERS DID JUST THAT! After a single treatment using the 1/3 bottle recommended for a hot tub, the leakage appeared to be completely stopped. The manufacturer mentions that without the drying-out period that is infeasible during cold weather I may need to re-apply come Spring. No worries. There are still 2 applications left in my bottle. Maybe I'll be motivated to update this review down the line. For now I have no compunction about giving this product my unreserved recommendation for pools and hot tubs. I'm a believer! ## Features - With pump running add FIX-A-LEAK slowly through skimmer or in front of any other suction intake. - After adding FIX-A-LEAK adjust suction to main drain. If this is not possible, the vacuum cleaner could be used alternatively, simply by placing the vacuum in deepest part of pool and connect to normal vacuum connection. Set filter valve to normal vacuum position. - FIX-A-Leak is very heavy and will sink to the lowest point rather quickly. It must be stirred back into suspension, either manually using a pool broom or mechanically with an automated pool cleaner every 4-6 hrs. during circulation of water. - After the leak has stopped and given the proper time to cure, (24-48 hrs.) you may return to normal filtration. Sand filters: Set filter valve to filter and resume normal operation. Backwash out unused FIX A-Leak as required. Other Filters: Reinstall filter into tank and Resume operation. Rinse out unused FIX-A-Leak from filter as required.*NOTE* Never let cartridges or DE elements be left to dry before they are cleaned. - Suction Leaks are usually known by air mixed with the water at the return fittings. In most cases suction lines only leak water when the filter pump is shut off. Normal Circulation will simply draw FIX-A-LEAK away from the leak and if the pump is shut off the material will simply not get to the leak. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B017B00LEQ | | Best Sellers Rank | #4,980 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #24 in Pool & Spa Replacement Parts | | Brand | Marlig Industries | | Brand Name | Marlig Industries | | Capacity | 2 Pounds | | Color | White | | Control Method | Touch | | Customer Reviews | 4.2 out of 5 stars 1,479 Reviews | | Efficiency | Highly efficient in sealing leaks in various materials and environments | | Installation Type | suction side | | Item Type Name | Fix-A-Leak By Marlig For Swimming Pool Spa Hot Tub Leaks 32 oz | | Item Weight | 32 Ounces | | Load Capacity | 2.1 Pounds | | Manufacturer | USA | | Manufacturer Part Number | 4316544721 | | Material | Sand | | Material Type | Sand | | Model Name | Fix-A-Leak 32 oz | | Model Number | Fix-A-Leak By Marlig For Swimming Pool S | | Other Special Features of the Product | Leak Sealing Ability | | Power Source | Fix-A-Leak By Marlig For Swimming Pool Spa Hot Tub Leaks 32 oz | | Required Assembly | No | | UPC | 802861225604 | | Warranty Type | Extended | ## Product Details - **Brand:** Marlig Industries - **Color:** White - **Material:** Sand - **Model Name:** Fix-A-Leak 32 oz - **Power Source:** Fix-A-Leak By Marlig For Swimming Pool Spa Hot Tub Leaks 32 oz ## Images ![Fix-A-Leak by Marlig for Swimming Pool Spa Hot Tub Leaks 32 oz,White - Image 1](https://m.media-amazon.com/images/I/512iy6HYEGL.jpg) ![Fix-A-Leak by Marlig for Swimming Pool Spa Hot Tub Leaks 32 oz,White - Image 2](https://m.media-amazon.com/images/I/81AmkKqkg1L.jpg) ![Fix-A-Leak by Marlig for Swimming Pool Spa Hot Tub Leaks 32 oz,White - Image 3](https://m.media-amazon.com/images/I/81nowLa1OKL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Do you think this might stop leaks in a backyard waterfall feature ?** A: It may in the pump and circulating pipe system, but I highly doubt it would stop a liner/tub leak **Q: is fix a leak hazardous to humans?** A: No. **Q: does this product work on intex above ground pool leak** A: Yes **Q: Will this damage my hot tub?** A: My hot tub is a twenty-five year old hot springs brand. It was leaking to the point where I was considering a new hot tub. This product solved the leaking problem. So far there appears to be no damage due to this product. I am very glad I used this product and would recommend it others. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product, follow instructions to the letter and allow for curing *by D***H on July 16, 2026* Don’t quite know how this works but it’s awesome, we have a 10,000 gallon in-ground fiberglass pool.
