Seachem Discus Buffer 250 gm
Seachem Discus Buffer, 250 gm
Our Price: $6.25
In Stock

Seachem Discus Buffer helps to replicate the ideal Discus environment (low pH & low GH (General Hardness)). Discus Buffer will lower pH and keep it lowered. Discus Buffer also softens water by precipitating calcium and magnesium.
  • Neutral Regulator and Discus Buffer can be used in combination to achieve a desired pH when performing water changes or adding top off water
  • Use 1 level teaspoon (7 g) for every 10-20 gallons daily until intended pH is reached. Thereafter, use once a month or with water changes as required to maintain pH.
Seachem Neutral Regulator 250 gm
Seachem Neutral Regulator, 250 gm
Our Price: $6.25
In Stock

Seachem Neutral Regulator adjusts pH to neutral (pH 7.0) from either a low or high pH and maintains it there. It softens water by precipitating calcium and magnesium while removing any chlorine, chloramine, or ammonia. The use of Neutral Regulator makes other conditioning unnecessary. To lower pH below 7.0 use Neutral Regulator with Discus Buffer. To raise pH above 7.0 use with Alkaline Regulator. All of these products will enhance and stabilize the freshwater aquarium environment.
  • Contains phosphate buffers and conditioning agents
  • Safe for all freshwater fish acclimated to neutral pH
  • In addition to Neutral Regulator’s superior buffering capacity, it will remove chlorine and chloramine, bind ammonia, nitrite, and nitrate, stimulate slime coat production, and buffer the pH to 7.0.
  • Use 1 level teaspoon for every 10–20 gallons once or twice a month (or as necessary to maintain a pH of 7.0.) Neutral Regulator may be added directly to the aquarium at any time.
