@Cathie G..Also...a small tank, like your 5.5g, is much less stable than a large tank. There will only be about 4-4.5g of water in it, and any chemical change will be extremely fast. Faster than you can get to Petco to get an approximate, at best, test result.I would suggest that you use your tap water, and of course dechlorinator.
The fish actually need the minerals in the water, and if you add a live plant it needs minerals too. Your pet shop uses treated tap water, so I think if it's a big difference in the pH of your local water and the filtered, you could actually kill your fish if you don't acclimate really slowly.
I know they seem expensive, but you really should get the API Master Test kit for fresh water. You will need it to know when your tank is cycled. Petco, etc uses test strips, and will only tell you "it's ok" or not. Kind of like round stickon temp/hygrometers. Accuracy is important. If you order it from Amazon, it will probably run you $20., vs probably $30 at Petco or Petsmart.
There is a very good fish forum called Fishlore, and they have several subforums devoted to only bettas. You would probably get a lot of good info from them.

You really need the Master test kit. Don't waste your money on test strips.
If you order it now from Amazon, you can test your tap water and see if you really need filtered. Remember, if a disaster happened to your tank, would you have enough bought water on hand to fill it?
