Have had a Caldera Martinique for three months. Started with Silk Balance and minimal chlorine (bad idea- water went cloudy a lot). Switched to chlorine (water stayed crystal clear but chlorine demand was extremely high). Switched to Spa Frog so that minerals and bromine would be constantly sanitizing water, without me having to dump in chemicals every day. But still, even with Spa Frog bromine cartridge all the way open (on "6"), I can't get, or maintain, a bromine level in the water (except for right after I shock it). (Water stays crystal clear though). Ran Sea Klear Spa Purge before draining and got an incredible ring of sticky oily muck at the water line. Wiped it off, ran the other half of the bottle, and kept wiping off the ring as it formed, until no more formed. Cleaned the tub and refilled, balanced, shocked, etc- even added Spa Perfect enzyme treatment- but STILL can't maintain any bromine level, with Spa Frog bromine all the way open (6). I took the front panel off, and discovered white spots/blotches in some of the clear tubing in the plumbing. White water mold, perhaps? Ran an entire bottle of Swirl Away (produced virtually no ring, this time), drained, refilled, dumped in nearly an entire GALLON of bleach, hoping the bleach would decompose the gunk in the lines- still nothing. Added an entire CUP of dichlor, and have run for an hour, but still have the same white spots and gunk visible in the clear plumbing. What do I do next, after all this, to get rid of that stuff in the lines, and try to finally overcome my sanitizer demand?
