Added 35% H2O2 in reservoir...oops?

I added 6 mil of H2O2 to my 20 gallon reservoir. Then I read it is supposed to be diluted to 3% and mixed at 3 mil/gal.
I just got done watering with it.

Why should the H2O2 be diluted first?

Should I ditch the solution and mix up a new batch?

Should I water the Coco Coir again to get all the H2O2 out?

That would be exactly the same dosage and won't matter. It's diluted in water either way. It's just safer to handle at 3%. Eyes skin etc.

Thanks!

Don't get that stuff on your skin. Been there done that. It's not as bad as a dry ice burn though. Those suck really bad.

Should use 0.5ml/L twice a week for general maintenance and rot prevention. So for a 20USG/80L rez you'd want to use 40ml. up to 4ml/L daily for a few days if root rot shows up. If you do mix it down to 3% first then multiply by 11 to get the same dose.

Just be careful with the 35%. Main thing is keep it out of your eyes so get some face fitting safety goggles for $10. If you get it on your skin just wash it off ASAP and no harm done. Don't be wearing your $2000 custom sneakers when handling it tho as it will fuck them up right now.
