For one gall do 1-50 and 1-100% water changes a week.
Take betta out. You can use container you bought him in as a changing cup.Just rinse everything in the tank( WITH OUT SOAP) . Just rinse it with warm water. I usually wipe and rinse again so there is no residue left.
Pour new water (with water conditioner) in his tank.
When you take betta out be careful if you are using a net. Don't damage his fins. Also when you couch the fish be aware it can jumped out. And when he is in his changing cup put a lid so it don't jump out. Some people using the net, some using a cup to scoop them. I think you would now your way..I am using a cup because i am afraid to damage their fins.
When you have him in his 1 gall bowl also live a space between the tap of tank and water level.
Now before you put him back in his tank .
While you have him in his changing cup with his original water, add new water to his cup a little bit..about 15% and let him get used to it for about 5 min. Do it a few times. This will let him adjust to new chemistry/temperature.
Usually when you change a betta you need to make new temp approx +-2-4*the same as his.You can let new water sit for 12-24 hrs . Put water conditioner , like you wrote you did, let it sit before you change him- this way new water temp will be the same as his, so you don't shock him with difference.
