Ok, so I got the HTH 6 Way DROPS kit: We have just plain water added to the pool at the moment, bought bleach and am going back for CYA and a dry acid now...unless I can find a small container of muriatic acid, we don't like the volatility of it.
Cl/Br--stayed clear
pH--at or above 8.2
CYA--stayed clear
Alk--450 ppm
Hardness--started off blue
