Seachem Neutral Regulator – pH 7.0 Buffer & Conditioner in One

Lock your pH at a perfect 7.0.

A drifting pH stresses community fish, and juggling separate conditioners and buffers is a hassle.

Seachem Neutral Regulator adjusts pH to neutral (7.0) from either a high or low starting point and holds it there — while removing chlorine and chloramine, detoxifying ammonia, and softening water. It does the job of a conditioner and a buffer in one, so no other conditioning is needed.

Seachem Laboratories has been a chemistry-driven company since 1979, developing its treatments in-house in Madison, Georgia. Neutral Regulator reflects that engineering: rather than making you dose a separate conditioner and buffer, its chemists combined both functions in one concentrated product designed to work with the wider Seachem buffer system.

1. Use 5 g (1 tsp) per 40–80 L (10–20 gallons), once or twice a month.
2. Dose daily at first if alkalinity is high, until 7.0 is established.
3. Best added by dissolving in replacement water at a water change.

Set it and forget it at pH 7.0. Add to cart.

Why Seachem Neutral Regulator

• Two products in one: adjusts and holds pH at 7.0 while conditioning the water — no separate dechlorinator needed.
• Concentrated, low-frequency dosing: 5 g (1 tsp) treats 40–80 L (10–20 US gallons) just once or twice a month to maintain neutral pH.
• Conditions as it buffers: removes chlorine and chloramine, detoxifies ammonia, and softens water in the same step.
• Built to work as a system: pair with Acid Buffer or Discus Buffer to go below 7.0, or Alkaline Regulator to go above.

Best For

Community freshwater tanks that need a stable neutral pH of 7.0 with conditioning built in — and as the neutral anchor when targeting a specific pH with other Seachem buffers.

What It Does

Adjusts and maintains pH at 7.0, removes chlorine and chloramine, detoxifies ammonia, and softens water. Replaces separate conditioning. To go below 7.0 pair with Acid Buffer or Discus Buffer; to go above, pair with Alkaline Regulator. Contains phosphate buffers; safe for freshwater fish acclimated to neutral pH.

Directions

Use 5 g (1 level teaspoon) per 40–80 L (10–20 US gallons) once or twice a month, or as needed to maintain pH 7.0. May be used daily at first in high-alkalinity cases until 7.0 is established. Add directly at any time, ideally by dissolving in replacement water at a water change.

Available Sizes

50 g, 250 g, 500 g, 1 kg, 4 kg

FAQ

Do I still need a separate water conditioner with Neutral Regulator?
No. It removes chlorine and chloramine, detoxifies ammonia, and softens water while holding pH at 7.0, so no other conditioning is needed.

How do I pair it to target a pH other than 7.0?
To go below 7.0, pair Neutral Regulator with Acid Buffer or Discus Buffer; to go above 7.0, pair it with Alkaline Regulator, following Seachem's ratios.

How often do I dose it?
Use 5 g (1 tsp) per 40–80 L (10–20 US gallons) once or twice a month to maintain pH 7.0. If alkalinity is high, dose daily at first until 7.0 is established.
