It's a highly concentrated base formula made to raise the pH of a nutrient solution and help hold it there, and that matters more than it sounds. Get the pH right and the nutrients already in your tank become available to the roots again, at every stage of growth.\u003c\/p\u003e\u003cp\u003epH decides how much of a feed a plant can actually use. Each nutrient stays dissolved and available to roots only across its own band of pH. Once a solution drifts too far acidic, some of those elements start falling out of reach. Calcium and magnesium are among the first to suffer. A plant can show deficiency symptoms in a tank that's full of both, because the nutrients are there and the roots simply can't take them up. This is nutrient lockout, and no amount of extra feed fixes it. Correcting the pH does.\u003c\/p\u003e\u003cp\u003eWhy does pH move at all? A nutrient solution never sits still. Roots take up some ions faster than others and release compounds of their own in exchange, and that slowly shifts the balance of the water around them. Your source water plays a part, and so does the nutrient itself, since many concentrates push a fresh mix down as they go in. A solution you set perfectly on Monday can be somewhere else by midweek.\u003c\/p\u003e\u003cp\u003eBeing a concentrate, pH Up moves a solution with small additions. Working in small steps is how you land on your target without overshooting it and having to chase the reading back the other way. You'll need a pH meter or test kit alongside it, as the reading is the only way to see where the solution sits.\u003c\/p\u003e\u003cp\u003e\u003cem\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e Avoid mixing pH Up with pH Down.\u003c\/em\u003e\u003c\/p\u003e","brand":"Green Planet","offers":[{"title":"500 ml","offer_id":67494104924318,"sku":"9327921001383","price":17.99,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/5261\/6094\/files\/Green_Planet_pH_Up.png?v=1793763524","url":"https:\/\/www.hydrooasis.com.au\/products\/green-planet-ph-up","provider":"Hydro Oasis","version":"1.0","type":"link"}
