I thought I would start a "after the build" thread started.
I did most of the build in 2014 but didn't get it wet till the last may.
I'm still digging around for old pictures of the build.
Here are a couple of today's pics.

RO/DI and saltwater mixing station.

Water change/settling tank

Sump is a work in progress and I plan on building one over the winter, utilizing a used 160 gallon acrylic aquarium.
I'm using a 100 gallon rubber maid at the moment. Much electrical re-routing and cleaning up needs to be done.

I'll have many hours into the system this winter fine tuning all the details.

When I have a moment I'll list out all the equipment I'm using to keep 450 gallons flowing and operating.
