leslies has a decent testkit under their name brand "complete pool care dpd test kit" but I think it's just a taylor kit because all of the agents are taylor. It does just about everything except FAS/DPD chlorine but you can get that in a sperate kit from leslies called the "chlorine (extreme high & low ranges)" for $21, you can do quite a few tests with this. I particularly like the PH & chlorine test in the leslies kit. I kind of use a combination of bens kit (233) and the leslies kit. It's about time to reorder a new kit from ben as most of my agents are depleted.

as far as your green pool, you need lots of chlorine and filter time but until you get a test kit you will not know what your chlorine level is.
