Product Information

Full details

Seachem Alkaline Regulator is an essential water conditioning solution for freshwater aquarium hobbyists who need to raise and stabilize pH levels between 7.1 and 7.6. Designed for alkaline-acclimated species like rainbow fish, this formula utilizes phosphate buffers and conditioning agents to create a safe, stable environment; however, users should be aware that the inclusion of phosphates can potentially stimulate algae growth if the aquarium is heavily stocked or improperly maintained.

FAQs

Can I use this with acidic-loving fish?

No, this product is designed specifically to maintain an alkaline pH of 7.1–7.6, which would be detrimental to fish that require acidic conditions.

Does it dechlorinate the water?

No, you must treat your water with Seachem Prime first to remove chlorine and chloramines before adding the Alkaline Regulator.

How often do I need to add it?

Add it daily until the desired pH is reached, then switch to a maintenance schedule of once monthly or during your regular water changes.

Is it safe for live plants?

Yes, it is safe for most freshwater plants, though keep an eye on algae growth due to the phosphate content.

Can I mix this with Neutral Regulator?

Yes, combining the two is an excellent way to target a specific intermediate pH range, especially when using RO or DI water.

Troubleshooting

pH is not rising as expected

Check your total alkalinity (KH). If your water has extremely low mineral content, you may need to dose slightly more or ensure proper circulation to distribute the buffer.

Algae growth has increased

Excess phosphates can feed algae; increase your water change frequency or use a phosphate-removing media if algae becomes a concern.

pH fluctuations occurring

Ensure you are using the product in conjunction with regular water changes to maintain the buffering capacity of the tank.

Pros and Cons

Pros

  • Effectively locks pH in the alkaline range
  • Provides essential buffering to prevent crashes
  • Safe for all freshwater fish acclimated to alkaline waters
  • Easy to dose with standard teaspoon measurements

Cons

  • Phosphate content may encourage algae growth
  • Not suitable for species requiring acidic (low pH) environments
  • Requires careful measurement to reach target pH safely

Setup, Compatibility & Care

To begin using the product, ensure your tap water has been pre-treated with Seachem Prime to remove chlorine and chloramines, as these can interfere with the chemistry. Add 1 level teaspoon (5g) for every 40–80 liters daily until the target pH is achieved. Once the desired level is reached, you only need to dose monthly or when performing water changes to maintain stability. For maximum tank health, supplement this treatment with Seachem Fresh Trace to ensure that the trace elements necessary for long-term fish vitality are restored to the water column.
