Take this for what it's worth....and what you paid for it, LOL.....I use 4 gallons of solution in my buckets. When your plants get larger and blooming it is easy for them to drink a gallon or more a day. Using only 2 gal will reek havoc on your ppm and pH when you get to that point.
Also if you use H2O2 you will kill all the beneficial bacteria you've been trying to establish. DWC can be done in a living bacterial environment or a sterile environment. In my opinion it is much easier to run a beneficial bacteria filled reservoir than a sterile one. Your mileage may vary, but you should be aware of these things.
Good luck.
