pond construction questions.

I use a retro fit that sits on the bottom. If you are going to use one of
them weight it down at more than the four corner tabs like some have. Mine
floated to the top to many times last year. This year I am going to cover it
with rocks if I use it at all. Not to mention the rocks keep the fish from
getting sucked into the bottom drain.

Hello all,

I have a few questions and hope someone might be able to help.

I have a Beckett pump, forgot the rating, but its outlet is 1.5 inch.
I've read that you need to push the water through 3 inch pipes. So if
I use adapters I can go from 1.5 to 3 inch. Would this be ok for the
pump, would I gain anything from doing this or should I just leave it
at 1.5 inch.

Home Depot sells 20 mil PVC liner. Is this any good. 17x18 for $169
Can I get something better and cheaper.

A pond store guy told me that instead of a bottom drain, I should just
run a pipe to the deepest part of the pond. The end of it would just
be a strainer/grill that prevents fish from getting sucked in. This
way I don't have to put the drain through a liner and worry if it
leaks. Any opinions/advice about this.

Thanks in advance.
