Aquarium Fish Stress Relievers
Aquarium stress is caused by overcrowding, improper water conditions and transitions to new environments; it weakens fish immunity, slows healing, and is a main cause of aquarium illness. Aquarium fish stress relievers are crucial when preparing your aquarium water, adding new fish, and in times of fish illness. (Aquarium salt, vitamin & supplements, and places to hide help prevent stress too.)
Aquarium fish stress relievers usually remove chlorine and other chemicals/metals in tapwater, but they differ from many conditioners by focusing on the healthy growth of a "slime coat", the first defense in your fishes' immune system. Stress relievers also repair damage to the slime coat caused by handling or external wounds.
