This size bottle gives you the best value if you test frequently
I have the full Taylor test kit that I use for both my pool and spa. I buy these larger bottles and use them to refill the smaller bottles in my test kit. The tips pull right off of the smaller bottles with a little bit or force. Use some gloves when transferring back and forth with this bottle or you'll get some nice yellowish stains on your skin with this product. Try to store this where the temperature is fairly constant and it's not in direct sunlight.
