Liquid Oxygen — Hydrogen Peroxide Tank Sterilising Agent

Hydroponic grower? For a sterile, disease free tank and healthy plant roots, use Oxy-Plus 11.9%

  • Hydrogen peroxide (H202)
  • Fights root diseases (like Pythium)
  • Oxygenates your root zone, improving growth
  • Increases nutrient uptake
  • Use to sterilise hydroponic systems and clean equipment

It's hydrogen peroxide (H2O2). When added to your tank, it quickly breaks down and releases oxygen molecules to:


1. Attack diseases, fungal spores and pathogens in your tank
2. Clean and sterilise grow room equipment
3. Improve nutrient uptake

Overall, you’ll get healthier, disease free roots and stronger, faster growing plants. To sterilise your system between crops, use it at higher concentrations.

Note: A 5 Litre bottle is available to buy in store only.

Swap To Silver Bullet Roots

For best results, swap to Silver Bullet Roots. It's like Oxy-Plus 11.9% but has silver ions! These silver ions:

  • Break down the protective barrier of bacteria
  • Make the hydrogen peroxide molecules more effective
  • Keep the H2O2 molecules active in tanks for up to 5 weeks!

Silver Bullet's so good that you hardly ever have to dose, and when you do, dose rates are stupidly low - by switching to Silver Bullet you'll save 55%!

The Science

Oxy-Plus contains hydrogen peroxide (H2O2). When added to your tank, it quickly breaks down and releases oxygen.

These extra oxygen molecules:

1. Attack diseases, fungal spores and pathogens in your tank
2. Clean and sterilise grow room equipment
3. Improve nutrient uptake

Overall, you’ll get healthier, disease free roots. It’s great for both preventing and treating root disease.

You’ll get stronger, faster growing plants, thanks to better nutrient uptake.

It’s fantastic for cleaning and sterilising your system, equipment and growing media between crops, too.

Questions & Answers

Have a Question?

Ask a Question
  • Can this be used with GHE? or is it best to stick with an optimum set for NFT - A/B, silcon, oxy plus & nitrozyme?

    The Oxy-Plus can be used with the GHE range of nutrients. We would not recommend using Oxy plus in a soil grow, or if you have introduced a beneficial bacteria product such as Trichoderma.

  • Can I use liquid oxygen with soil, if so I leave my water to sit for at least 24 hours with an air stone and pump submerged before I add my nutrients then feed, would I be best to add oxygen with my base nuts or to add it to my plain water and pump for 24 hours?

    We would not advise using Oxy-Plus in soil, as it will kill all beneficial bacteria in the soil.

  • i use an air pump to oxygenate my nutrient, would using liquid oxygen increase my oxygen levels further? i am aware that all friendly bacteria is killed when using h2o2 products, but since vita link max(my preferred nutrient) dosen't really need the bacteria to break down the nutrient into forms the plant can use, is it worth trading friendly fungi for increased oxygen and cleaner rootzone conditions? i use clay pebbles and have recently read fungi does'nt colonize in clay anyway, unless i add coco at a min 20%.

    Oxy plus would potentially help with this, but you would need to add it often to your tank . It may be as beneficial to use Root Rot Stop, or Pythoff as an alternative to Oxy plus to keep the root system healthy.
