Yep I learn allot from down under..they take this very serious and darn good at it too.

Oh by the way I am using rain water, I got 100 gallons last 2 days from roof.
Our city makes our water with chlorine and fluorosilicic acid in it so it is not good
for my guts much less the plants and fish

Yea they are worried about our health and our teeth so they use that acid which is
a toxin left over from mining a certain product.
