How do I test the hardness of my aquarium water?

You can test the hardness of your aquarium water with strips, also called dip tests. For these tests, you collect a sample of your water in a small receptacle. Never dip strips into the aquarium itself. The strip will change colors based on water hardness.

How can I make hard water at home?

Pour 500 milliliters of distilled water into a calibrated beaker, water level touching the 500 milliliters mark in the beaker. Add half tablespoon of epsom salt to the distilled water.

Can Cory catfish live in hard water?

Maintenance and Care. Because these catfish come from the tropical regions of South America they prefer warm, slightly hard water with a pH between 6.0 and 8.0 as well as a water hardness level between 5 and 19 dGH. The ideal temperature range for Corydoras is between 68°F and 82°F.

How do I fix the alkalinity in my fish tank?

The fastest, easiest way to reduce alkalinity is to dilute the aquarium water with purified, low-mineral water. Reverse-osmosis or RO units produce water with almost no dissolved minerals. You can add this water to the aquarium to water down the overly alkaline water.
