Many tropical community fish do well around pH 7.0, while some Amazonian species prefer 6.5 to 6.8, and others like mollies and swordtails range around 7.2 to 7.5. This product offers a practical way to approach those numbers, with a formula that aims to be gentle on fish and plants.\u003c\/p\u003e\n\u003cp\u003eQuality and safety matter. The formula is phosphate-free and does not feed algae growth. It slowly neutralizes alkaline substances that cause higher pH, helping you maintain a stable environment as you monitor and test weekly. The product contains sulfuric acid at 9.6 percent as part of its chemistry, and API emphasizes using all products as directed to achieve best results.\u003c\/p\u003e\n\u003cp\u003eWith API, keeping a tank you can enjoy becomes simpler. You can focus on watching fish explore, plants unfurl new growth, and the evolving color and motion of life in your aquarium, rather than guessing at pH alone.\u003c\/p\u003e\n\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What does API pH DOWN do?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It lowers freshwater aquarium pH to the desired level and is formulated to be safe for fish and plants when used as directed.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is API pH DOWN safe for fish?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, it is designed to be safe for fish and plants when you follow the directions and monitor pH with a test kit.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"API","offers":[{"title":"Default Title","offer_id":53561461604681,"sku":"B0002AQMV4","price":17.65,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/1781\/9465\/files\/api-ph-down-bottle-closeup.jpg?v=1766444271","url":"https:\/\/petvita.co.uk\/products\/api-ph-down-freshwater-aquarium-ph-reducing-solution-4-oz","provider":"Petvita","version":"1.0","type":"link"}
