Yes - was $1,000 when I bought it. Price has gone up (like everything else I guess)
The kit:
There's some kind of probiotic starter bacteria used to get the pond going when it's new. Good bacteria to populate the filter, break down fish waste, etc. I waited a few months before adding anything live. Then there's the chemical for the tap water - removes chlorine & chloramine. Just a splash of that once in awhile. Does not take much water to keep it topped up. Very low maintenance.
Here's the kit
I bought plants at my local nursery - there's nothing funky here. I did buy 4 aquatic plants online. 2 survived, 1 is really thriving. The heat is not a factor at all. Neither is the cold this past winter. The fish eat all bugs and chew on the algae all day - I do not feed them with supplemental fish food. They take care of cleaning out the pond. It's also packed with snails (you can get those on Amazon too, weird, right?). Check out trapdoor snails on Amazon. Buy one lot of them and they breed like crazy - you never have to buy again.
