Keep pH between 7.2 and 7.6 and avoid stacking additional copper products, which is what causes copper staining or a green tint.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \n    \u003cdiv class=\"frogbar-faq-card\"\u003e\n      \u003ch4\u003eCan I use this with my FROG system or a salt pool?\u003c\/h4\u003e\n      \u003cp\u003eYes. The 90-Day Algae Barrier is built to run alongside \u003cstrong\u003eFROG sanitizing systems\u003c\/strong\u003e and works equally well on standard chlorine pools and salt pools. Any pool with a working skimmer can use it.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \n    \u003cdiv class=\"frogbar-faq-card\"\u003e\n      \u003ch4\u003eCan I install this myself?\u003c\/h4\u003e\n      \u003cp\u003eYes, this is one of the easiest pool treatments to apply. With the pump running, \u003cstrong\u003edrop the pod into the skimmer basket\u003c\/strong\u003e, let it dissolve over about 24 hours, and you are done. There is no mixing, measuring, or pouring, and the pool is swim-ready roughly 30 minutes after dosing.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \n  \u003c\/section\u003e\n  \n\n  \u003csection class=\"frogbar-cta\"\u003e\n    \u003ch2\u003eOrder the FROG 90-Day Algae Barrier From PST\u003c\/h2\u003e\n    \u003cp\u003eAuthorized King Technology dealer with the 01-10-6800 in stock and ready to ship.\u003c\/p\u003e\n    \u003cdiv class=\"frogbar-perks\"\u003e\n      \u003cspan class=\"frogbar-perk\"\u003eFree Shipping\u003c\/span\u003e\u003cspan class=\"frogbar-perk\"\u003e30-Day Returns\u003c\/span\u003e\u003cspan class=\"frogbar-perk\"\u003e90-Day Algae Guarantee\u003c\/span\u003e\u003cspan class=\"frogbar-perk\"\u003eAuthorized King Technology Dealer\u003c\/span\u003e\n    \u003c\/div\u003e\n  \u003c\/section\u003e\n\n\u003c\/div\u003e\n","brand":"King Technology","offers":[{"title":"Default Title","offer_id":44126696865857,"sku":"PST-01106800","price":31.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0633\/1623\/0209\/files\/PST-01106800.jpg?v=1783492423","url":"https:\/\/www.pstpoolsupplies.com\/products\/frog-90-day-algae-barrier-20k","provider":"PST Pool Supplies","version":"1.0","type":"link"}
