50%=1ml/L
35%=1.7ml/L so a .7 increase for a 15% decrease,

I'm decreasing 17.5% from 35%@1ml/L so add .7 for the 15% which makes 2.4ml/L and throw in .1 for the spare 2.5% which makes 2.5ml/L

but I see the logic of 35%=1.7 so 17.5% makes 3.4.

Londoners datasheet states 5ml per 10 Litres which is .5ml per Litre ??

I'm confufled.

Your figs are OK.

Dosage instructions on H2O2 container labelling vary wildly. I have 2 jugs of 50% H2O2 here, one is labelled 1ml/10L, the other is labelled 2ml/5L (and why they didn't just say 4ml/10L is kinda curious). Go figure.

I use H2O2 50% @ 1ml/L in everyday nute & clone watering solutions, redosing the tanks every 3-4 days. When treating a system which has a large pathogen load because it has not been treated before, a one-shot dose of 50% @ 10ml/L followed in 3-4 days with a schedule of regular dosing at 1ml/L works well.

For use as a general cleaning surface steriliser, 10ml/L in a spray bottle works well, but use care not to breathe the spray mist nor get it in your eyes. yowchie. Might be smarter to apply it with a sponge, wearing rubber gloves, of course.

No kidding, I got my shipment in today and one was a bit over pressured. Some spilt on the floor and I accidentally stepped in it. Had a white foot for about an hour and it feels like i lost a layer of skin. I love putting it in my nutes and seeing little o2 bubbles on the bottom though.
