I use Magnesium Oxide (MgO) prill beads to bring pH to 8.7 PERMANENTLY. Simple and works for decades, never dissolves, never wears out and never needs to be replaced. I have used this in 1000s of consumer's homes for a onetime retail cost of $40. Placed in a glass, plastic or ceramic containers. Removes pesticides, bacteria, heavy metals, pharmaceuticals, chromium VI, Ecoli, arsenic, radiation, black mold, etc. Contact me for more info.
