This summer we had our vinyl liner replaced. The literature that came with the Tara Liner states "do not shock prior to closing". It recommends avoiding using Trichlor at any time and never allowing the FC > 5.0. I have used the TF 100 test kit for a couple of years now so my water chemistry is good. I am concerned about only adding algecide prior to closing and not shocking also. What do you think?
20X40 vinyl liner in ground, SWG, T100 sand filter in West Tennessee. I use a smartmesh pool cover. thanks in advance for your help.
