I went to my local independant pool guy and had my water tested. Vedict..... my kit is defective... (actually they are strips). I actually have twice as much CYA as needed. Supposedly, the reason why my chlorine isn't holding is due to the excessive sunny warm days that have been experiancing over the past month or so. He said to expect to use close to twice as much chlorine as I usually use.

Question: What test kit(s) would you recommend ? I'll see if I can order them online somewhere.

Thanks !
