So do you remember what the concentration of the peroxide was that the lab came up with? Found this
"Concentrations of around 60ml of 3% H2O2 (30ml of 6%, 15ml of 9%) in a 250 Litres (66 US G.) tank directly applied (usually via a syringe) slowly over 5 minutes onto a clump of algae will kill it and then rapidly be diluted and converted into harmless oxygen and water."
I think the qualifier there is that it will rapidly be diluted and converted into oxygen and water. In the first post it sounds like you have the water sitting around for at least 3 days.
Makes me wonder about the validity of the test.
