I went to Wal-mart and bought Jungle test strips because my LFS only has copper tests. Anyway, I was looking for the API Master Kit or some liquid tests, but the only liquid they had was API pH tests. Instead, I got a Jungle Ammonia test kit with strips, and then the 5 in 1, too. I know strips are less accurate, but at least I can still have an idea for my water. Buuuut... I'm having second thoughts. Is it even worth opening the boxes, or should I take them back to Wal-mart while I still can? I thought about ordering of the internet, but I figure the shipping and the fact that something could happen to it in the mail means I ought to leave that alone. Plus, it'll take a while and I have really limited cash. What should I do?
