I have a 2010 Hot Springs Vanguard tub that this forum helped me set up. Thank you. I love my hot tub. I/ we (the wife and I) use it 4-5 days a week. Mostly just me. It will be two months tomorrow. I am using the Bromine System. It has been very easy. I knew nothing coming in. I am using the Taylor K-2106 to monitor my waters health. I have clear water, no smell and no foaming problems. I have not had any skin problems that I've suffered with public pools. I have added only an ounce or two of bleach over a month ago. Very minor adjustments only a couple of times with baking soda and/or muriatic acid. This particular model has five filters in the filter well. One primary and the others appear to be just soldiers. Today I went to clean the filters and found them very clean. All had some very minor particulates and the primary had some discolor at the bottom. I gave them all a hot water rinse. they all look very clean (white) including the primary which I rotated out to a secondary position. I chose not to use the filter cleaner I had. I was afraid it might introduce a foaming problem. Would you insist I use the filter cleaner? Should I use some bleach just because?
