My CYA tests have been reliably measuring around 50 all summer. Today I tested it and the dot is gone even prior to hitting the 100 mark. I haven't added anything but bleach and acid since the last test so I know my level isn't that high. I'm wondering now that the water temp is down in the mid 50's if the temperature affects the results of this test? Is that possible?
On another note (and possibly related). I'm noticing some calcium buildup on the inside of the test tube. Is there a good way to clean that out? Would a few drops of muriatic acid in 10ml of water do the trick?
Other measurements:
FC - 4
pH - 7.6
TA - 70
ch - 310
Bot - 30
