Hi Binoy;

Read the test kit page in my signature; get an OTO/phenol red kit and report pH and chlorine results tomorrow. And ADD SOME CHLORINE before your pool turns green. Tomorrow evening, add at least 2 gallons of PLAIN 6% bleach per 10,000 gallons in your pool.

And when you say "foamy", we ask, "what have you added?". Like Anna requested, please give us a list of everything added in the last 6 weeks.
