I'll try to find the trichlor but I'm rural so don't make the drive to larger town often. I do have the 40lbs of 3" chlorine tablets and will can use them (instead of returning to the store) if that is advisable. Is there any way they would work? Haven't seen any "trichlor" in any of the suppliers available to me.

Tried subscribing but if paypal is the only option I will not be able to do that. Is there any other payment method? I have all major credit cards or can mail check, cash or MO.
