Apply very small amounts to the solution you wish to decrease the pH of and mix well to allow the pH reading to stabilize before adding more. Repeat until your target value is reached. For recirculating systems, check the pH daily. Recommended pH for most plants is 5.5-6.5. Keep out of reach of children; store in a cool, dark place.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposition:\u003c\/strong\u003e non-mineral formula; the label lists hydrogenated water and no fertilizer nutrients\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 6 gallons (22.7 L)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade by:\u003c\/strong\u003e General Hydroponics\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp class=\"sku-info\"\u003e\u003cstrong\u003eModel # \/ SKU:\u003c\/strong\u003e hgc722002\u003c\/p\u003e","brand":"General Hydroponics","offers":[{"title":"6 Gallon","offer_id":47513077874879,"sku":"hgc722002","price":221.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/9334\/4191\/files\/gh-9597620781247-800.jpg?v=1791162994","url":"https:\/\/www.dsgardensupplies.com\/products\/general-hydroponics-pro-ph-down-professional-ph-adjuster-6-gallon","provider":"DS Garden Supplies","version":"1.0","type":"link"}
