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%!

can i use this in a wilma kit to prevent root rot as my wilma kit is converted to allow the roots to grow down into the reservoir. i have air stones in their but will this help further?
The Pythoff can be used as a preventative measure in this kind of system. It is used at 1ml per 10 litres of nutrient solution.
