Seachem Marine Buffer

Struggling with low pH or unstable alkalinity in your saltwater aquarium? Seachem Marine Buffer helps restore balance and maintain a stable environment for your fish and invertebrates.

Marine Buffer is designed to safely raise and maintain pH while supporting proper alkalinity levels. Unlike simple pH boosters, it works to stabilize your system over time helping prevent dangerous swings that can stress or harm your aquarium.

Ideal for routine maintenance or correcting imbalances, this is a simple and effective way to keep your saltwater tank stable.

How It Works 

Low pH and unstable alkalinity can happen due to:

• Waste buildup
• Low buffering capacity
• Natural biological processes

Marine Buffer works by:

1. Increasing carbonate alkalinity
2. Raising pH to a stable range
3. Helping resist future pH swings

Result: A more stable, balanced aquarium

What It Helps Fix

• Low pH levels
• Unstable alkalinity (KH)
• pH swings in saltwater tanks
• General water chemistry imbalance

Why It Matters

Stable pH and alkalinity are critical for fish health and overall system stability.
Sudden changes can cause stress, reduce immunity, and lead to long term issues.

Perfect For

• Saltwater aquariums
• Fish only (FOWLR) systems
• Routine water parameter maintenance
• Correcting low pH conditions

How to Use

Add as directed to gradually raise and stabilize pH and alkalinity.
Always test water parameters before and after dosing.

Pro Tip

Don’t chase numbers aim for stability.

Use a test kit to monitor KH and pH, and make gradual adjustments to avoid sudden swings.
