How would you measure this? I only have one plant that I would need to use it for right now. I wanted to soak bark in it for one normal sized Phal plant. 1 ml per 10 gallons of water? I wouldn't use anywhere near 10 gallons! So how am I supposed to measure THAT? Maybe it's way too concentrated to attempt using.

An easy way to measure out 1 ml/10 gal or 1/10 (.1) ml/gal is to use an eye dropper. Using water, find out how many drops are in 1 ml. Then divide by 10.But if I may ask, why are you using Physan 20 (P20) on your plant? Plant roots do not like P20. I have tried P20 in a hydroponic system and the evidence was very clear, the roots don't like it. If you have Pythian or some other fungus, Actinovate Fungicide works great. It is a bit pricey but worth it. For algae use an algaecide.

Can this be used to sanitize ro water purifiers? seems to have the same ingredients as the sani-system sachets.

I am not sure I use it in my outside fountain to keep it clear.

Does Physan need to be kept cool? Mine was accidentally left out in the hot sun for a few days. I’m hoping it hasn’t lost its disinfecting power.

I have left my bottle out in the Arizona temperature and it never seems to have effected the product.

Is Physan 20 the same thing as Physan 20 Fungicide? As a first time buyer of Physan 20, I'm a bit confused the various sellers naming inconsistencies.

Yes, Physan 20 is a fungicide. I use it to prevent algae. I suppose some sellers are just more descriptive with their titles than others. However, they are the same.
