The spin lab that is used in store for pool and spa water testing, tests the levels of each chemical in the water, then gives instruction on what chemicals to use to balance the water. It is a free testing that we provide to the clients and new customers in our area. Our program stores all information from your water sample, so we can correctly track the chemistry of your water. The spin lab takes about 2 minutes from walking in the door, to getting a printed report of your water chemistry and how to resolve the issue, if there is one.
