Just received my K-2006 and tested it out. The past week my water has been looking pretty okay but I've also been 'guesstimating' bleach additions every couple days and brushing the sides down (generating puffs of yellowish-brown dust that I assume are those nefarious mustard algae) so the water is still mostly clear and blue.
FC 0.2 PPM
Calcium Hardness 240
CYA 100+?? (I guess this is why I've had to keep adding chlorine... yes I was using tablets before I joined the forum)
I just added about 3 lb. soda ash to adjust the pH - can I add the chlorine simultaneously or do I need to allow time for the soda ash to mix in first?
