Description
Additional information

Alkaline Regulator™ adjusts pH to the alkaline range of 7.1 to 7.6 and creates the optimal environment for alkaline-acclimated species such as bosemani rainbowfish and other rainbow species. For a complete freshwater setup, pair Alkaline Regulator™ with Fresh Trace™ to restore essential trace elements.

The Science

A number of popular freshwater species originate from naturally alkaline lakes and rivers, where pH sits consistently above neutral. Rainbowfish, in particular, are found across the rivers and lakes of Australia, New Guinea, and Southeast Asia, many of which are moderately to strongly alkaline. Keeping these fish in neutral or acidic water can cause gradual stress and reduce their long-term health and colouration, even when other parameters appear to be in order. Alkaline Regulator™ uses a phosphate-based buffering system to raise pH into the appropriate range and maintain it there between water changes.

For aquariums where a specific pH between 7.1 and 7.5 is required, Alkaline Regulator™ can be combined with Neutral Regulator® using the ratio chart below to reach a precise target. Always dechlorinate tap water with Prime® before water changes to ensure the buffering system works without interference.

pH Targeting Ratio Chart

When using Alkaline Regulator™ and Neutral Regulator® together to reach a specific pH, refer to the chart below. This chart assumes the use of unbuffered water such as RO or DI water. If using tap water, treat it as a starting guide and adjust from there.

Neutral Regulator®	Alkaline Regulator™	Target pH
4	1	7.1
2	1	7.2
1	1	7.3
1	2	7.4
1	5	7.5

Advice

Use 1 level teaspoon (5 g) per 40 to 80 L daily until your target pH is reached. Once the desired pH is established, maintenance dosing of once a month or with each water change is sufficient. Always dechlorinate tap water with Prime® before water changes. To target a specific pH between 7.1 and 7.5, combine Alkaline Regulator™ with Neutral Regulator® using the ratio chart above as a guide. To lower pH below 7.0, use Neutral Regulator® alone.

Heads-up

Alkaline Regulator™ contains phosphate buffers, which may contribute to algae growth in aquariums with elevated nutrient levels. Monitor phosphate levels if algae becomes a concern and consider increasing water changes or plant density to manage excess nutrients. This product is formulated for freshwater use only and is not suitable for marine or reef aquariums. Always adjust pH gradually to avoid stressing fish.
