So yeah, I just got this kit so I can use it for my new 5g I'm going to get in a few weeks. Right now, my new betta fish is in my 1.5g and I know it's not necessary to use the kit for something so small, but I was so excited, I wanted to test it out xD I was just wondering how I should clean the tubs 'cause I just got the fish two days ago and the ammonia tested out 0. The next day, it seemed like it was .25ppm and today, I believe it was .5ppm. I did a 50% water change today, and the readings still seem to be .5ppm. I tested my regular tap water, and it came up reading the same thing.. So... I'm assuming the tubes need better cleaning than just a quick rinse.. and I'm assuming it's okay to clean them with chlorine, but I wanted another persons opinion before I just jump into it, ya know?
