Also, if the first aid hydrogen peroxide is something I should avoid using.

Actually, if it is labeled hxdrogen peroxide at 35%, it should be H
2O
2 and nothing else. Otherwise, or if there are any additives, - they should figure on the label. Low concentration H
2O
2 may use some stabilizers, but I've read studies where "stabilzed" low concentration H
2O
2 was used to disinfect setups .
As it is a powerful disinfectant and antiseptic, it kills every living organism but the plants, if used in the right concentration (dilution).
Though, if using hxdrogen peroxide one should be aware that all micro organisms in the systems get killed- also beneficial organisms or fungus die. As I add Trichoderma harzianum to my reservoirs, I am obviously avoiding the use of H
2O
2.
