Because science. I was testing all sorts of levels in my small fish tank. Ph, ammonia, nitrites- and a few other things. All the bad stuff? Yeah all of it was really bad. One was so bad it was actually off the color chart of the test. I need a bigger tank to help keep some of this stuff under control, but today I crushed a lot of the harmful water condition sources. Oh well, once I get a job I think I'll devote a paycheck solely to buying a big bad ass tank. And a couple hardy and sacrificial fish to get the nitrogen cycle started right this time. I'm learning. =P on the bright side- my ph is right!
