The Problem

Water authorities add chlorine and chloramines as disinfectant in the tap water supplies to the consumer. Chlorine and chloramines are harmful for fish even in concentration as low as 0.05 mg/L. These common additives found in tap water may cause gill damage in the fish, leading to gill lesions. The lesions thicken the gill filaments which result in the fish’s inability to use oxygen and release carbon dioxide. The condition eventually leads to fish death.

The Solution

Hydra Aqua Dechlorinator is an effective pond water dechlorinator, which safely eliminates chloramines and chlorines from the tap water before adding in the ponds with aquatic life.

My pond is new. Why is an additive like Hydra Aqua Dechlorinator is necessary?


  • Posted by Aj Edgar on Monday, 27 January 2014

Hydra Aqua Dechlorinator removes these chemicals present in the tap water. You may use Hydra Aqua Dechlorinator under following situations:

    • Upon initially filling the pond with tap water
    • Adding tap water to make up for evaporation loss
    • When doing partial water change

I wanted my newly dug up pond be filled with water as soon as possible.But friends advised me against using tap water because of chlorine in it. Someone suggested using a Dechlorinator. Now I know I did the right thing for my pond.
