No you're right
@WaterGardener - this started out to be about SPC and then suddenly we were talking about baking soda and all the dangers of life and ... I don't know. I was just being friendly and sharing something that I do that's EASY, requires very little THINKING, and from my experience is perfectly SAFE for my fish and pond. I literally just toss it by the cup full onto the surface of my pond. No measuring. NO WORRYING. I also use it on my waterfalls and rocks. Hate string algae on your rocks? SPC is your friend.
I am just suprised at how many people will go to a pond store, buy a product off the shelf and use it in good faith, but they have so much trepidation over buying and using the EXACT SAME PRODUCT that isn't labeled with the fancy pond picture.
We've bought liquid 35% hydrogen peroxide - yes, you read that right - THIRTY FIVE PERCENT - for years and used it for all kinds of things. You can dilute it as necessary for things like teeth brushing or wound care, or you can use it full strength like I did in a garden bed when I was told the soil in that bed needed to lay dormant covered in solar plastic for at least seven years to kill off the bacterial wilt that I had gotten from a cucumber plant that I bought at the nursery. I soaked that garden bed in full strength H2O2, waited a few days and then planted right in that soil. Never had a problem ever again. I've used it for a variety of fungal and downy mildew issues in the garden, spray my tomato leaves with it to control blight... you name it, I've done it. It will indeed burn like a mother if you get it on your hands full strength, but you won't die.
And yes
@j.w I brush my teeth with 3% H2O2 every single day. I just open the bottle and pour it on my brush. Brush my teeth. Rinse my brush and pour more peroxide on it to kill off the germs that might have been in my own dang mouth. haha! We also put it in a nebulizer and use it at the first sign of cold, flu, sore throat, etc. But you want to be sure you're buying food grade for that - the drug store variety can have stabilizers.
Thank you for coming to my Ted Talk.
