Kartoffel is a wild betta species called Mahachai betta.


3 day old water:
1. Tap water in a bucket
2. Add water conditioner and stir vigorously, kinda like making a lemonade.
3. Leave the water 2~3 days alone. You can cover it with something, too, if you want to avoid dust.
4. 1~2 hours before the water change, I add a heater in the bucket and match the temperature to the tank’s temperature. Kartoffel’s tank is 26°C or 79°F.
5. Optional almond leaf water: Boil dechlorinated water; I use the bucket water. Pour the boiling water in a glass container. Add crushed almond leaf in the container. Stir. Leave it alone for an hour or two. I add just a little bit of this almond water during the water change.

You don’t have to do water changes like this. However, this is the safest way I know for a betta.
