Navigating Bangalore Tap Water: Keeping Your Fish Safe

Bangalore's water supply can vary wildly depending on whether you rely on Cauvery water or a local borewell. For aquarium hobbyists, this unpredictability means you must be vigilant about water treatment.

The Threat of Chlorine and Chloramine

Municipal water is heavily treated with chlorine and chloramine to make it safe for human consumption. However, these chemicals will instantly kill your fish and the beneficial bacteria in your filter. Always use a high-quality water conditioner before adding tap water to your tank.

Borewell Water and Hardness (GH/KH)

If you use borewell water in Bangalore, it is likely very hard with a high pH. While African Cichlids and Guppies love this water, sensitive fish like Discus or Neon Tetras may struggle. Consider mixing in RO (Reverse Osmosis) water to soften it.
