MATALA BIO-ACTIVE STONE 1.4 INCH MBAS-14
MBAS-14 ~ 1.4" Bio-Active Stones
High surface area porous media is ideally used as a last step in the biofiltration process and plays a great role to stabilize pH and mineral content while further polishing and refreshing water quality.
For pH stabilizing use 40-60 lbs per 1000 gallons of water. Replace every 12 months
For mineral enrichment and polishing use 20-40 lbs per 1000 gallons of water.
Refill every 2-3 years as mineral contents are slowly releasing in the water.
