The quotation marks, and different colored font indicate that the P vs Fe comment was not mine, but in fact Chromophore's.

Allow me to translate for you.
The PH chart seems to indicate that in order to use Phorphorus the chemical symbol for which is, P.
The PH must be high enough to almost lock out Iron, the chemical symbol for which is, Fe.

And the point of that post was that you should go back to tap water.

And do not let the tap water sit out for a day and a half.
That is an old wives tale that just won't die.

All that does, is allow the dissolved air to escape.
Stagnant, airless, water is not good for plants, or critters.

The Chloramine, that is almost universally used as a water disinfectant today is a compound and not a gas, it does not escape when water is left to stand.
Nor do you want it to.

It protects against anaerobic bacteria, and is not taken up by roots.

Run your water right from the tap.
Preferably through an aerator, then add your amendments, check the PH, and apply immediately.

It's a free education and mostly accurate.
