Stains on the vinyl liner are also treated by adding a mineral sequester. Persistent stains might need to be treated with an \u201con contact\u201d product. These must be applied directly to the stained area of the pool. If the stain is on the bottom of the pool, applying the product directly on the stain can be tricky, but possible.<\/p>\n<h3><b>Low pH<\/b><\/h3>\n<p>Due to the acidic nature of our tap water and our rain. We tend to suffer more from low pH pool water than from high pH pool water. Fortunately, correcting the pH balance of your pool water is quite simple. All you need to do is add pH Increaser (also called soda ash and base). But before you add pH Increaser be sure to get your Total Alkalinity balanced first. Once the Total Alkalinity is balanced, the pH can be adjusted more accurately.<\/p>\n<p><a href=\"https:\/\/paradisepoolsmart.com\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft wp-image-134 ls-is-cached lazyloaded\" src=\"https:\/\/paradisepoolsmart.com\/wp-content\/uploads\/2021\/01\/taglogo.jpg\" alt=\"Paradise Pools Mart\" width=\"50\" height=\"71\" data-src=\"https:\/\/paradisepoolsmart.com\/wp-content\/uploads\/2021\/01\/taglogo.jpg\" \/><\/a><br \/>\n<strong>Paradise Pools Mart<br \/>\n<\/strong><a href=\"https:\/\/www.youtube.com\/channel\/UClTEREL5vde6OZVFyrEdgNA\">Our You Tube Channel<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>15ft x 30ft x 54in Oval Caspian Above Ground Pools are economically priced and backed by a 20 year warranty from Hollowell Industries, Inc built in the U.S.A. for over 35 years.
