This will be my 5th year on BBB with only $15 of chlorinating liquid monthly (during the 7-month summer swim season) for my 16,000 gallon pool, no shocking, no other chemicals (except a small amount of acid once a month). This is in spite of my pool having 2000-3000 ppb phosphates. The truth will set you free (of labor and headaches) and keep your wallet full.
