Why is blk water basic instead of acidic?

Recently I came across a brand of water called blk, named for the black appearance of the water caused by the addition of fulvic acid. The manufacterer's website states that it is "exceptionally pure artesian spring water" with the addition of the company's blend of fulvic and humic acid. Now, we all know that the PH of pure water is 7, but if we add acid, wouldn't that make it more acidic? Apparently not, seeing as the manufacturer's website also states that the PH of blk water is 9, making blk water more basic than regular water. I would think the fulvic/humic acid's addition would make the PH acidic, not basic. Can anyone explain this?

I bought a cheap LED flashlight that charges with a decently sized solar panel. I opened it up and found that it holds 3 AA rechargeable batteries and has a reasonable amount of free internal space, I was thinking of putting a hole just large enough for a female mini-usb port.The 3 batteries are 1.2V Ni-Cd 500mAh.And there's a black ... thing ... that says:IN819WXDHand the resister is brn blk blk gldlet me know if ya have a solution [=

is this right? trying to set up 6 servos to arduino uno...

I am new at this and i suck!!! i am trying to run 6 hobby servos to my arduino uno- i am powering it with an external power source (12v adapter) and on my bread board all servo blk/red wires to the power + and the ground to -. The power on the bread board is going onto the vin diode on my arduino, neg to the ground on my arduino and all the other color wires from the servos to the numbered diodes on the arduino. Is that right? every time i run it i get the "because a USB was drawing too much power from your computer" response.  i know the 12v is a bit excessive to power up the servos, but does anyone know a better approach this? much appreciated let me know thanks, makemelook
