Oh! Forgot to post earlier that if there's not a pet store near you where you can buy water conditioner try looking at Walmart. =]
The following water conditioners can be found at any Walmart with a fish section:
AquaSafe by Tetra company
Start Right by Jungle company =]
I know for sure that those are at EVERY Walmart. =] Check around where all the fish food and the cartons (that look like milk cartons except they're dark blue, hot pink, and yellow) of aquarium salt are. They're in opaque (not see though) bottles with twist on and off caps.
At Walmart in the fish isle the AquaSafe is in a yellow bottle and the Start Right is in a white bottle. =]
I bought the Start Right by Jungle Co. that I have from Walmart. =] The best thing about water conditioner in general is that you only need a little bit every time you change your water! For my Start Right I only use half a cap-full for my 5 gallon aquarium! =]
I also bought my 5 gallon Aquarium Kit by Tetra Co., heater, aquarium salt, betta pellets, and gravel at Walmart because it's MUCH cheaper there! =] Soon I'll be getting my decorations and fake plants from Walmart too. =]
The only things I've gotten from a pet store (only because I was in the store and needed them/they didn't have the one I wanted at walmart) were my gravel vaccum, my net (the ones at walmart were too big I was afraid a betta would get tangled), my test kit (that coincidentally DOESN'T test for ammonia!!! GRRRRR curse my stupidity!), and some melafix (because they were out at walmart that day for some reason). =/
I got all the supplies in the "Supplies I didn't get from a Walmart" paragraph from a Petsmart. =] Soon I'll be getting my bettafrom Petsmart but only because I found one I absolutely ADORE there, all the bettas at petsmart are half off for a while, and the bettas at walmart are usually really sick.
Walmart NORMALLY has Mellafix if you're interested in getting that too. (it's supposed to help with finrot and stuff) They were just out of it the day I was there.
