Beneficial bacteria thrive in the soil and help create a balanced soil that will be exactly 6.5. It may start a little lower or higher, but over time the bacterial colony is going to equalize it to 6.5 in the absence of an external source causing an increase/decrease in ph. If supersoil weren't balanced, the colony wouldn't thrive and you wouldn't get the results people see from it. This may be why when some people alter the formula too much it doesn't work as well. Want proof? Start with water not ph 6.5, brew aerated organic tea, and check the ph in a day or two once the bacteria are really thriving. It'll be exaclty 6.5 no matter what ph you started at. One of the reasons with good compost teas you don't have to even check ph of the water.
