Thank you for you kind words, they really mean a lot.
I wanted to get into this hobby long before I actually did just because of the price factor. So because of that I tried thinking of ways to save money and still be able to have the big peninsula tank that I've always wanted.
The stand was a no brainer "DIY" but I didn't think about making my own sump until I decided to have a filtration room. After that it was just looking at every type of sump I could think of to get ideas. And since it's not going under a tank really opened up the size possibly. The sump is far from done, lots of things to do on it yet before I can start pluming the internals of the sump but it's getting there. I wouldn't have built one if I hadn't found out about pond armor. Sure I could have used fiberglass or just epoxy but there is the possibility of something in those that might not agree with a reef system long term. Pond armor was made specially for fish. It is non toxic uncured and cured.
I'm hoping the the live "rock ruble canal" (trade mark pending [emoji6]) plus filter socks is a benefit. in theory it should work well. All the overflow water from all three tanks will have to pass through the rock to get to the socks. marine pure block are great but pricey rock ruble is cheap and I have the room to do the canal.
Hopefully I have steady progress from here on out.
I think the best benefits of a coral~rock rubble canal would be used with a Calcium reactor to help raise the pH before it returns to your DT.
It will fill up with detritus overtime
