Peter, thanks for your reply. I put in the .9 gal of bleach last night. Went to Wal-Mart for the Stabilizer which reads Cyanuric acid=96% and inert ingredients=4%. Is this ok to use or does it need to be 100% Cyanuric acid? Will add some Baking soda this morning and test my my alk and chlorine and post the results.What is the best way to add the baking soda? Thanks for your help.
