I've seen reference on other threads to a technique for Spa maintenance that seems to alternate Dichlor and Bleach as a fairly fuss free maintenance program. I believe it was chemgeek who mentioned it, but the exact details were not given. I just refilled my tub and am due to purchase chemicals. I HATE bromine tablets/feeder and shocks and clarity and the plethora that my spa place would have me believe I need to be adding every week. Please advise on what this Dichlor/Bleach method is!!
