Hi all, and thanks in advance for any feedback. So I have a 400 gallon Sundance Spa and keep a close eye on it with the Taylor K 2006 kit. I refilled it in January last as it seemed to be eating my chlorine up as fast as I put it in. The CYA had rose I assume....... Anyhow, now I am more in control after purchasing the kit. So since January, there is minimal usage ie 2 people using for 15 -20 mins individually in total. (we prefer tubbing in warmer months) I have been keeping on top with chlorine (trichlor) Realized that i can use a lot less than my company told us to add!!!! But here's the thing, my water is spotless and chrystal clear. Has no smell. My water is stable with SI 0.1. My pH is 7.6, Alk is 110, Hardness is 150, FC is 4.4 but the combined chlorine is between 0.2-0.4. The CYA is 90-100. Should I be worried about these chloramines and CYA levels? I shocked the tub with MPS last on March 10th for CC of 0.4, on March 14th it was CC 0.4 so I shocked again with more MPS (using as per guidelines on bottle/tub size). I can't seem to get rid of the chloramines. Yesterday it was again 0.4 and no one has used it in over a week. Also what do people do when they go on vacation? I am going away in May for 2 weeks. If I don't add the chlorine daily or every few days the water will turn for sure!!!!!
