Lower or increase the pH in your aquarium with ease! Maintaining the proper pH of aquarium water is important to ensure a healthy environment. Changes in pH can be caused by the breakdown of waste or local tap water with low pH or low alkalinity. Correct pH® maintains the recommended levels in your aquarium to prevent harmful fluctuations.

ADD ONE TABLET TO EACH TEN GALLONS (40L) OF AQUARIUM WATER. USE TETRA® TEST STRIPS TO DETERMINE THE pH LEVEL AND TREAT AS NECESSARY. TO AVOID DRASTIC pH CHANGES, CHECK pH AFTER 24 HOURS BEFORE ADDING MORE TABLETS.
NOTE: FOR AQUARIUMS 40 GALLONS OR LARGER OR WITH LOW ALKALINITY WATER, DISSOLVE TABLETS BEFORE ADDING TO AQUARIUM.
* CORRECT pH® WILL MAINTAIN LEVELS FOR SEVERAL WEEKS DEPENDING ON FISH LOAD AND WATER QUALITY. HARD ALKALINE WATER MAY REQUIRE A SOFTENER.INGREDIENTS: SALT, BUFFERS, POTASSIUM SALT
