Problem #2 item 4.
"Initially, your stabilizer-eating bacteria and biofilms will STILL be active in your pool. So, do NOT use stabilized chlorine to start with -- you could end up making your problem worse, faster than you make it better. This means NO dichlor powder. Use bleach or calcium hypochlorite only."

I will have to take a pic of the #50 bucket of the 1" tablets I saw. I may have read the ingredients wrong.

The bleach I have is 12.5% concentration. I buy it from the feed store. I get deposit bottles. When I come back with the bottles I get my $6 back. I understand he fills them there himself. The chemical company is Funshine. They are 1 gallon bottles. With the deposit taken into account it is about the same price as the 10% Pool Store For pool only bleach, but everything at the feed store is cheaper. Accessories are less and I can also get the dog food and the chicken feed there as well. It is win win for me. If there is a good argument for the 10% bleach with the throw away bottles I would love to hear it. Even if my 12.5% ends up being the same concentration as the 10% bottles I would not mind since they use the bottles over and over all summer instead of throwing them away.
