Seachem - Betta Basics 60 Ml.

The 60 ml container of  Seachem Betta Basics  is a scientifically formulated water additive designed to provide the optimal environment for both betta fish and delicate live plants. The solution helps to remove any harmful chlorine, chloramines, and ammonia that can negatively impact your aquatic pets. It buffers the water to a pH of 7.0 and promotes vigorous health and growth.

Directions:

Use this formula with each water change. For best results also use 2 to 3 times per week. Add 1 capful (5 mL) per each 1.25 L (1.25 quarts) of aquarium water. In Betta-only bowls (i.e. no plant) use 1 capful per 4 L (1 US gallon) with regular water changes.
