Seals minor leaks in most in-ground swimming pools & spas. Can seal leaks losing up to 1" of water per day in a 15,000 gallon pool. No need to empty pool or spa. Fast acting - usually stops leaks in 24 hours. Lo-Chlor Leak Sealer is an amazing special compound that has been developed to help seal minor cracks and leaks in swimming pools. A leaking pool is every pool owner's nightmare. Lo-Chlor has developed an easy way to plug minor leaks. Leak Sealer has a very high pH (about 12) so when you add it to your pool it takes on the pH of pool water (between 7.0 and 8.0). It now no longer functions as a liquid and starts to solidify in the presence of oxygen at the site of the leak. To ensure best results, please follow the instructions from the manufacturer.
Note: Not for use in vinyl liner pools.
