Well I am doing a ebb and gro system and was told I need to use H202.....now my local hydro store doesn't carry this product in stock so instead I had to go with Fox farms Oxygenator which they do carry. Now I will be using this in a 55 gallon drum per 50 gallons and was a little confused on the ratio I should be using. I have heard of 1ml per gallon and I have also heard 5ml per gallon.....I was just curious if anyone has tried this product and if so how much I should use and how often to replenish.
