Keep your aquarium water pristine for your african cichlids. Water buffers are a perfect way to mimic their natural environment and keep them healthy and full of vibrant color! African cichlids require different water conditions than most municipalities or wells provide.
Seachem offers a wide variety of products to help accomplish that. Use Prime/Safe with every water change to ensure the water you are putting into your tank is safe and free of heavy metals and chloromines.
