What do you think about air pumps

The hydrogen peroxide you get at 3 % at drug stores has a stabilizer in it and is not food friendly. H2O2 will give up more of it O as the solution heats up. I use 30 % H2O2 and mix 11 water to 1 H2O2 and use that at a rate of 3 mil per Lt of solution. You can have too much O in the solution if added with H2O2 - you might bleach the roots.... H2O2 is great for house plants that have gotten root rot...

Ive used 3% H2O2 for years without any problems. You just need to use it in the right concentration. I use 1 Teaspoon per gallon of water and have for many years. Peace

I avoid using the common 3% hydrogen peroxide you normally find at drug stores. This is because such low percentage solutions are unstable, and chemicals are added to the peroxide to keep it from breaking down before it can be used. I did a little research because I did not know what chemicals were used for this, or if the plants uptake these chemicals, or if there was a health risk associated with any of these stabilizing chemicals.

Hydrogen peroxide is usually stabilized with acetanilide. Acetanilide is a synthetic compound that was first used for its fever reduction and pain killing properties in the late Nineteenth Century. For many years it was utilized as an alternative to aspirin to treat various ailments, but large-scale medical use stopped when the toxic side effects of consuming acetanilide became apparent. This was enough to make up my mind to use 35% hydrogen peroxide instead.
