Seachem Laboratories Reef Buffer Aquarium Water Treatment, 8.8 oz

If holding a steady pH in your reef tank has felt like a constant battle, Seachem Laboratories Reef Buffer is built for exactly that job. This 8.8 oz aquarium water treatment is intended primarily for reef systems, where Seachem notes that maintaining a pH of 8.3 is often difficult. It gives you a controlled way to bring your water chemistry where you want it without the guesswork, so dosing day becomes a routine instead of a worry.

• Designed to raise the pH of your reef system to 8.3, the target many reef keepers aim for in a marine tank.
• Used as directed, Seachem says you can raise pH without fear of accidentally overshooting to a dangerous level, so you dose with more confidence.
• Also raises carbonate alkalinity, addressing two key parts of reef chemistry in a single treatment.
• A blended product, not just sodium carbonate, which is how Seachem distinguishes it from simpler additives on the shelf.
• Works hand in hand with Reef Builder, which Seachem recommends for raising alkalinity when pH is not a problem.
• Gives you a focused tool for the specific demands of a reef system rather than a general-purpose freshwater additive.
• The 8.8 oz size suits smaller setups or keepers who want a manageable supply for routine dosing.
• Pairs naturally with Seachem's MultiTest: Marine pH and Alkalinity so you can check your numbers before and after treating.
• Comes from Seachem Laboratories, a name reef and marine hobbyists turn to for water care.
• Supports the stable water conditions your corals and marine life rely on day after day.

For best results, test first with Seachem's MultiTest: Marine pH and Alkalinity, then dose Reef Buffer as directed to bring your pH toward 8.3 while also lifting carbonate alkalinity. When pH is already where you want it and you only need more alkalinity, reach for Reef Builder instead so you are not pushing pH any higher. Used thoughtfully and according to the label, this 8.8 oz supply of Reef Buffer helps you give your reef the consistent, well-buffered home it needs to flourish.
