The head groundskeeper told me to tell ya'll that the 12.00 harbor freight pump is fantastic.
He got one last year and liked it a lot so this Spring when it went on sale again for 12.00 he bought another.
He installed the new one at the end of the dog leg, the old one is to the left of the statuary frogs by the big waterfall.
It has several couplings/fittings and all you need is a small piece of garden hose to hook it up.
He works great for getting little waterfalls going around the pond for aeration as well as interest.
They are only about 250 gph ...so very economical to use.
It's on the bottom right, under the rock.
The other one is next to the statuary frogs. Hard to see from this distance, but he rather have lots of
little falls going on than one big roaring one...
