Hey Pool Owners! Are you damaging your pool liner by using shock? Any chemical that clumps on or around your pool liner can damage it. So if you’re using shock, consider pre-dissolving it in a bucket of water. Then add it to the pool by slowly pouring it around the edges. This will help reduce the risk of bleaching your liner.
