More info on the liner. we purchased the liner from breadhurst aquatics,
it was pre cut and in a bag without any manufacturers labels or
information or instructions. I am suspicious that it may not be pucker
because of this but at the time I trusted the supplier (why wouldn't I)
since this I have seen all the pre cut liners in my area at other aquatic
shops which have all the labels etc. we were told that it is PVC liner.

if you see all of my posts you can see that we will find out soon by
testing if its the liner. there is a slight possibility that we have
contamination from some industrial units behind out house.at that point I
will be in touch with trading standards or environmental health depending
on how these last few tests go.

Are you oxygenating your water? Low oxygen will cause a fish kill.
