Okay, the guts. It's quite simple. Here is the skimmer where the 2 pumps are housed. The net is there to catch leaves, so you just pull it out and dump. Then you see a set of brushes that catches fine media. Just pull it out and hose.
Here is a picture of one of the waterfalls. Where you see all that gravel, you can plant stuff in there. There is a trough so that it's always wet at the bottom. You can plant stuff like creeping jenny etc so that it climbs and hides the plastic and the open portions. You can see the media in there. This falls unit holds about 100 gallons alone and it it packed with this media for surface area for the bacteria to colonize. Around the falls unit I will have to fill with topsoil and we'l l be planting shrubs and ground covers all around.
Moved some fish and got some more
That big one is 2 feet.
And a FTS with fish. For perspective, the biggest fish you see there is 24"
The pond company will be coming back today to add some feature boulders around the pond and make a cave in the pond for the fish and tidy up things a bit.
