Hagen Nutrafin pH Adjusters

Nutrafin pH Adjust Up and pH Adjust Down are two great products that safely increase or decrease pH. Nutrafin pH adjustment products have been developed to safely and effectively optimize pH levels. The proper pH range is imperative for fish and plants. Reproduction, appearance and overall health are correlated directly to pH levels. We recommend that you use the Nutrafin wide range pH Test regulary to properly monitor and adjust pH. You can be assured that these products will slowly increase or decrease pH levels without creating pH shock. Neither product contains phosphates and both products are for freshwater use only.
