I was searching for water testers so I had some on hand, but the LFS's here are kind of expensive. I think there's a mini kit at Pet Smart for around $6 though it doesn't really say on the website what it all comes with. The LFS's did mention they will test my tank waters for free, so I was wondering what I should use to carry the water in. Keep in mind I'm walking 2miles to have this tested so something like a cup is out of the question. I don't know what could contaminate the water like if I stored it in like a tupperware bowl. Would just a plain plastic baggy work? This should only be temporary since I feel it's important for me to have those testers on hand at home so I can provide my buddies the top care they deserve, but I'm broke atm. My tattoo and setting up my 10gal tapped out my spendings for the month.
