    How much do you guys add to your ebb flow reservoir? I use about 20 gallons. How much h2o2 should I add and how often? Thanks.

    Is this the brown bottle stuff or the Brand H202? If its the brand 12 of a cup every three days. If it's the "brown bottle" stuff from like the dollar store, then 3/4 of a cup every 3 days.

    1.4ml per liter every 3-4 days

    holy crazy answers, 5ml will do 5 gals. so 20 ml for 20 gals. and it only lasts for like a day. so 20 mil every other day.

    k seting this mystery strait! AL B FUCT says for 29% H202 use 7ML to 10ML per gal. and for 35% I would go 5ML to 7Ml per gal.
    keep in mind that there isnt a cap on how much to use. ive gone as high as 15ML per gal 29% for heavy root issue and with no
    negative plant signs.

    I actually was curious about the amount people have had luck with when adding to their res, but I have a dwc so I do not know if I should add it or not because the roots would be getting splashed with it all the time. Or is a small amount not damaging?

    Search for H2O2 on here ! You will find tons of info... I use 5ml per gal. At a top up rate of 20% per day. Its NOT gone in a day or two. If your using it as prevention or minor oxygenation. I went as high as 20ml/gal to deal with root rot. It saved my
    plants for sure. Everyone has an opinion on this for sure.... But please just do some research of your own and you will understand best practices using H2O2.
    Good luck.
