Happy Ducks

Would Recommend

I bought this to use as a small pond for my ducks to bathe in after they put a hole in the kiddie pool we were using. It's the perfect size for my 3 ducks and much more durable.

Nice shape and size for small garden

Would Recommend

I appreciate that they didn’t try to box or wrap in my plastic to ship. It got here quickly and was exactly as expected. I’m using it for a small big garden and should be perfect.

The Goldilocks of preformed ponds

Would Recommend

This is a great starter pond —not too big. Dug hole and had it filled in an afternoon, even with more than 40 rocks in the way. Wish it had a shelf, but hey those rocks will come in handy now.

How wide is the pond in the middle? I see from the description that it is 26 inches wide (ends) I plan to set a fountain in the middle of the liner.

What size pump does it need?

can this pond be placed on top of ground with rock surronding it
