Guard'n'Aid OxyPlus 12% Hydrogen Peroxide – Oxygen Booster & System Cleaner

Guard'n'Aid OxyPlus 12% – Hydrogen Peroxide Oxygen Booster for Hydroponics

Most feeding mistakes in hydroponics aren't made through ignorance. They're made at eleven o'clock at night, by a tired grower, eyeballing a splash from a big bottle into a big tank and hoping for the best. The chemistry of growing is well understood. The psychology of dosing gets almost no attention at all — which is odd, because it's where most of the damage is done.

That's what makes OxyPlus quietly clever. The chemistry is straightforward: a 12% hydrogen peroxide solution that releases extra oxygen into your nutrient water and keeps your system clean. The thoughtful part sits on top of the bottle — a built-in measuring chamber that lets you squeeze up the exact dose, check it by eye, and pour. It removes the guesswork at precisely the moment guessing is most tempting.

🫧 What OxyPlus Does For Your Grow

• More Oxygen at the Roots: Increases the oxygen content of your nutrient solution, helping roots stay white, healthy and hungry for nutrients.

• Keeps Systems Clean: Helps prevent the slime, algae and bacterial build-up that clog pipes, drippers and pumps.

• Preventative Against Pythium: Helps guard against root rot in warm reservoirs, where oxygen levels drop and problems start.

• Useful for Germination: A dilute solution can be used when germinating seeds to help protect against damping off.

• No Residue: Breaks down into water and oxygen, leaving nothing behind in your system.

How To Use It

Always follow the dosage on the label. As a general guide, growers typically add around 5ml per 10 litres of fresh nutrient solution, with small top-ups of about 2ml per 10 litres a few times a week to maintain oxygen levels. For best results, pair it with an air pump and air stone to keep your reservoir moving.

One important note: OxyPlus shouldn't be used alongside organic fertilisers or beneficial bacteria products. The same oxidising action that deals with harmful bacteria will also knock back the good ones — so it belongs in mineral hydro and coco systems, or as a cleaner between crops.
