Description
Looking after a smaller freshwater tank, or just want to try a trusted conditioner before committing to a bigger tub? Seachem Laboratories Neutral Regulator in this compact 1.8 oz size is an easy place to start. Despite the small package, it does the same dependable work: it adjusts your aquarium pH to neutral, which Seachem lists as pH 7.0, from either a low or high starting point, and then works to maintain it there so your fish enjoy steady conditions.
Why this 1.8 oz size makes sense:
Perfect for smaller freshwater tanks, nano setups, or trying Neutral Regulator for the first time.
Adjusts pH to a neutral 7.0 whether your water begins too low or too high.
Maintains that neutral pH, which the brand says helps stabilize the freshwater environment.
Softens water by precipitating calcium and magnesium for a gentler profile.
Removes chlorine and chloramine from tap water, so it is ready for your fish on water-change day.
Detoxifies ammonia, helping protect your fish when ammonia would otherwise climb.
Acts as your conditioner in one step, since Seachem notes its use makes other conditioning unnecessary.
Pairs with companions: Acid Regulator or Discus Buffer to drop below pH 7.0, or Alkaline Regulator to raise above it.
Even in the travel-friendly 1.8 oz size, Neutral Regulator carries the full toolkit your freshwater fish appreciate: a neutral pH target, softer water, and tap water free of chlorine and chloramine, all handled together. For a more complete freshwater routine, Seachem suggests Fresh Trace to restore trace elements and NutriDiet Tropical Flakes to help your community fish stay healthy. This size is also handy as a backup to keep in the cabinet for a quick top-up between larger orders, or for a second small tank. Just measure to your aquarium volume following the label directions, and let this little container do its quiet job of keeping your fish’s water balanced. For a low-commitment way to bring Seachem’s neutral-pH conditioning to your tank, the 1.8 oz Neutral Regulator is a friendly first step.
