Conditioning aquarium water

It is used for conditioning aquarium water; the acid from the leaves slowly lowers the pH of the water as it seeps into the water. It also helps to reduce the ammonia level in the water by converting ammonia into less toxic substance ammonium, thereby decreasing the burden on the filter.

For most fish species to spawn, they need lower pH, precisely what Indian almond leaves offer.

Sometimes, even after the labor, the livebearers, such as guppies, platies, etc., are left to rest in a separate tank to recover. Flavonoids released from Indian almond leaves have anti-inflammatory properties that help to rejuvenate the tired fish.

You can refrigerate this water in a tight lid jar for several months. Dosage should be an ounce (approx. 30 ml) for every gallon (approx 4 liters) of aquarium water; make sure to add the extraction after every water change.

Final Note
