Pools plagued with heavy metals get relief from metal and stain treatments that remove existing stains and protect against future metal fall-out stains.

An ozone system is a critical component to water clarity.  Ozone helps metals and minerals form chains big enough to filter out, so ozone's ability to clarify the water greatly reduces the need to buy chemicals.

Give heavy metals to the bands.  Keep crystal clear pool water for yourself.  Rock on!
