The UltraClear® Buffer Block pH Stabilizer stabilizes pH, increases water hardness and adds essential calcium needed for healthy fish bone growth. It also enhances the growth and survival of beneficial bacteria for a healthy, beautiful pond. Great for snails! The Buffer Block will stabilize the pH and increase water hardness and alkalinity in your pond. Ponds with low or no buffering capacity (low alkalinity & calcium carbonates) become pH unstable, resulting in wide swings of the pH. Adding UltraClear® Buffer Block pH Stabilizer helps prevent this from happening. Application Instructions The Buffer Block treats ponds up to 2000 gallons. Place the Buffer Block in the main water flow of the skimmer, filter or waterfall. Lasts up to 3 weeks. Replace when dissolved. Warning In case of eye contact, immediately flush with plenty of water for at least 15 minutes. Get medical attention. In case of skin contact, wash thoroughly with soap and water. In case of ingestion, do not induce vomiting. Get medical attention immediately. SKU UPC Size 32400 743053324005 110 grams
