You should never add a concentrated hydrogen peroxide solution directly to your reservoir. Always reduce the concentration first by mixing one part of the 35% concentrate with eleven parts of water.
So if you take one ounce of food grade peroxide, mix it with eleven ounces of water to get a 3% solution. Always use fresh distilled water if possible for best results.
The recommended amount of 3% solution of peroxide per gallon of water in hydroponics is around 3ml per liter or 2-3 teaspoons per gallon of reservoir water. Please note that we are talking about the diluted solution, NOT the 35% concentrated peroxide.
 
ok you just repost what I said 3ml of 3% per liter I guess just going to grow a plant to test keep adding more tell I kill it my guess probably takes a lot to kill it closer to 1% of water being hydrogen peroxide I know i can put seeds in 1% and crack really fast tanks for trying to help that is the general guide that seems to be floating around
 
If your going the sterile res rout. Go buy some pool shock. H202 is 100000% the cost to keep the res clean. .01grams per gallon pool shock. 1lb bag last years.

I used to use 35% h202 for sterile. Cost me 45$ a bottle and I needed 2 per grow. Also does not work as good imo. Need way more re applies than pool shock.

Every 3 or 4 days. That's. 0.01 grams. So you need a scale that will do .00 grams.

I just have a scoop that is about the correct size. Just throw a scoop in every 3 or 4 days. 10 gallon res. So 0.1 grams every 3 or 4 days in my 10 gallon res.

It's what I used to use but I generally never measured and just tossed 1/2 a cup into my rdwc I built. Then I went to a dirty res and everything was grand after that.
 
In my opinion you can easily double dosage.
The strongest mix I ever used was 1 part 3% h2o2 to 4 parts of water but I also heard that clean 3% h202 don't hurts the plants I mean leaf's and root as well.
Try and let as know.
Bless
