Seachem Neutral Regulator is a freshwater water treatment and pH conditioner that:
Adjusts water pH to neutral (around pH 7.0) whether your water starts above or below that level.
Softens water by precipitating excess calcium and magnesium.
Removes chlorine, chloramine, and detoxifies ammonia, helping make water safer for fish.
Contains phosphate buffers and conditioning agents and is safe for freshwater fish acclimated to neutral pH.
It’s especially useful if you want to stabilize your tank’s pH around 7.
How to Use
Dosage (dry powder): ~5 g (≈1 level teaspoon) treats 40–80 L (10–20 US gal) of aquarium water.
Add it once or twice a month or when performing water changes — or daily initially if needed to bring pH to neutral.It can be added directly to the tank or dissolved in water first.
There’s also liquid versions available if you prefer dosing liquids over powders:Seachem Liquid Neutral Regulator / Seachem Liquid Neutral Regulator 500 ml
It’s designed for freshwater tanks only and aims for pH about 7.0.
Because it contains phosphate buffers, some aquarists avoid heavy use in planted tanks (phosphate can encourage algae growth).
If your goal is just dichlorination or ammonia detoxification, general water conditioners like Seachem Safe or Prime are often a simpler choice , Neutral Regulator focuses more on pH adjustment.
