Neutral Range pH Buffer & Stabilizer For Marine & Freshwater Aquariums KENT MARINE pH STABLE safely increases the total alkalinity (buffering capacity) to provide a stable pH level in the system. Does not promote algae growth.
Draw 3 cups of water from aquarium in a separate clean container, add 1/8 teaspoon of KENT Marine pH Stable, and mix well. Disperse this amount into the aquarium for every 20 gallons of water to raise alkalinity about 20ppm. Wait one hour to re-measure the alkalinity, if low repeat procedure.
Measure and adjust pH as necessary with KENT Marine pH Control Plus or KENT Marine pH Control Minus.
When using Reverse Osmosis water or tap water that is very soft (low total or general hardness, or GH), use KENT Marine R/O Right to increase total dissolved solids (GH) to the proper value.
