How do you dispose of the chemicals used in the api master test kit? I do not have a chemical waste plant near where I live, ive heard of people washing it down the drain and then watering it down, but i have a septic tank and dont know if thats a good idea.

Just wanted to let ya'll know. A good friend of mine alerted me that the normally around $30 test kit is on sale for $18. Not sure how long the sale will go on. I'm getting mine in the mail tomorrow! :D

Hey guys! I'm the type of person who likes to ask a lot of questions. Since yall have been so helpful, I figured I'd as a few more :] So I picked up an API master test kit the other day, and I had a few questions. What's the best way to read results? I just held up the tube in the white parts...
