The carbonates in water help stabilize pH. But both the heat and aeration of spas drive out carbon dioxide. Consequently, pH in spas tends to rise. If pH is outside the recommended range it can cause problems: Swimmer discomfort (Bloodshot eyes and irritated skin can be signs of a high or a low pH,) Equipment deterioration (High pH forces minerals into solids and forms scale. A low pH will corrode equipment and the spa interior,) Chemical Inefficiency (Chlorine (and to a lesser extent bromine)...

Buying Guides
Above-Ground Pool Buying Guide
Above-ground pools give anyone the fun of a pool in even the smallest backyards. Since these pools don't require a permanent installation, homeowners and renters can purchase pools that are compact, moveable, and easy to install. This guide will help to decide whether a hard wall pool that stays outside year-round or a frame pool or ring pool that can be stored for winter is the best fit for you.
Make sure you have the right kind of location with sunlight, away from trees, and easily visible from your home. Learn the shape of pool that will work best in your yard. And learn about which accessories you'll need, such as covers, ladders, thermometers, pool lights, and filtration systems.
