Well, we decided not to redo the 'pond' really just used as a fountain

to clean, but will wait for now.

It is a good idea to plan well for a bottom drain when you do decide
to replace the liner. I buried my filter barrels and can't drain
them, but have to use a shop vac to clean them. OTOH my pond bottom
drain is gravity flow through the filters and pumped from the third
barrel. Most of us in this part of Georgia don't have our ponds on a
nice hill that would allow draining everything by gravity flow, but
that is a nice feature, if it is practical for you.
