"I switched to these dip strips a couple years ago when my (then 7 year old) son got his own tank. The accuracy is comparable to the full spectrum test kit I was using, and it was very easy for my child to use and interpret the results himself. We have repurchased many times. I highly recommend you tear off the color chart and tape it to an index card, completely covering it in clear box tape. It is nearly impossible to keep the paper dry otherwise. Your welcome."
