I have a Dynasty spa which i have owned for approx 20 years. I always use a liquid chlorinator by Pool Essentials but recently started using a 1 inch tablet chlorine tab in a floater. (the floater chlorine last longer) Over the past 30 days my spa pillows developed a tar substance which is very sticky and black junk appears on the tub near the edges of the pillow. It is difficult to get off and i usually use a paint thinner to get it off. I replaced 2 of the pillows and the new ones did the same thing within several days. I suspect it is the pool chlorine tablets that are too strong and actually melting the pillow. I have switched back to my old liquid chlorine to see if this is the case. The chlorine levels tested fine each time, however, the PH dropped a bit. Thoughts?
