I simply am at a loss for words. I did not have a chance to read this entire thread in it's entirety yet but I am just in shock. This is the greatest pond build I have EVER seen and I can see no corners were cut on this. When I read things like this it brings a smile to my face seeing how much time blood sweat and tears go into something of this magnitude. I am a 21 year old novice in this hobby, clinging to stingrays, aspiring to have something of this caliper in my future.
True motivation for myself as well as the rest of the fish keeping community, kudos to you my friend!
Edit: I also wish you lived closer I would pay to visit a pond like this!
Everything is running great. We did finally install our divider wall a couple weeks ago. The males where getting to aggressive with the females, one of them decided that instead of latching onto her disk he would latch onto her gills. So yeah, he had to go on time out.
Also have a 75G that sits on top of the pond now which is where the pups will go when they are born.
