pH Control Plus

Directions: First, measure alkalinity (buffering capacity, carbonate hardness, or KH) and adjust to the appropriate level. Next, adjust and raise pH by drawing 3 cups of aquarium water in a separate clean container, add 1/8 teaspoon of KENT Marine pH Control Plus, and mix well. Disperse this amount into the aquarium for every 20 gallons of water. Wait 24 hours for the pH to stabilize and adjust further, as needed. Caution: This is a concentrated product! When in doubt, less is better. It is recommended only to adjust the pH up 0.2 pH per day.

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.

To adjust alkalinity (buffering capacity) use KENT Marine Superbuffer-dKH or KENT Marine pH Stable.
