Myself, hubby and close friend have managed to build our inground pool. We finally dropped the liner and have begun filling with water. We are installing the pump and filter this weekend and hope to have everything plumbed and ready to go. My question is what's next. I have read through the ABC's but I still don't know what to do next. Do I add chemicals or test then add? What is the best test kit to buy? Thanks in advance for trying to help!
