You did OK except the master test kit I got was missing ammonia number two bottle and I had two wide range bottles so now I gotta figure out how to get that ammonia number two bottle just a hassle my first order, but I will order again. Update: So I’ve been working with Ben and Derek. These two guys have been wonderful. My order was a little messed up but they got me all hooked up and it was very quick. I will definitely order from playitkoi.com again. I didn’t have a big issue, but they worked very hard to make it right and do it in a timely manner. Thank you for your awesome customer service. I look forward to working with you again.
