Tap water can be a useful starting point when its composition suits the animals and unwanted substances have been addressed. Drinking water does not automatically mean suitable aquarium water. Start with your supplier’s quality report and measure GH, KH, pH and nitrate at your own tap.
Check these three things
- Disinfection: establish whether chlorine or chloramine is used. Treat any disinfectant with a suitable aquarium product according to its label. Standing water does not reliably remove chloramine. If neither disinfectant is present, this alone is not a reason to add conditioner.
- Composition: compare readings with the species and animal supplier. A household salt-based softener produces different water from an RO filter; do not assume softened water equals soft aquarium water.
- Preparation: use a clean aquarium bucket and bring water to a suitable temperature. Keep a routine reproducible once it works.
Water containing unwanted substances does not become suitable simply by adding minerals. Investigate the substance and an appropriate alternative. RO can help, but both the unit and prepared output need checking.
After problems following a water change, record the volume, source and treatment. Check temperature, ammonia and nitrite too. The timing of deaths alone cannot identify copper, pH or a mineral deficiency.
