Yay! Thanks so much for the reply! I love this forum.

Answers to your questions: I am using just a cheap standard pool kit for testing - rainbow guard is the manufacturer and it is just a liquid drop kit. Nothing special. If you could supply links to a place where I can purchase a reliable kit, as you mentioned, I would appreciate that.

Ok, now chemicals I've put into my pool since this began: shocking at least once a week with either 52% calcium hypochlorite or I've also used 73% calcium hypochlorite. I have a chlorine floater that has 3" 99.4% trichloro-s-triazinetrione. After I do any of this, and test my chlorine the following morning after adding to the pool at night, the chlorine is gone..... I've also put in about a gallon of monosodium cyanurate monohydrate 35%, about a liter of phos free (can't find chemical name on the bottle??), and about 16 oz of poly[oxyethylene(dimethyliminio)ethylene(dimethyliminio )ethylene dichloride] 60%.

I will follow the directions you gave me in your last post, and if you have any more to add, I'm all ears!

When I add the bleach - what is the best way to add it?

Thanks so much!!!!!
