Little Update.
Sorry it's taken so long to get some pics up. Been extremely busy. I took today off to play with the tank and see my daughter's play this afternoon.
I got the new primer and LRB from Sanitred last week. Finally got around to scraping all the previous sealant down/off. I re-primed the glass, and now I'm waiting for it to setup, which is "feeling" like it's any time now. It's still a little too tacky to apply the LRB. I'll have the glass re-sealed today.
Pics below are the background in progress. It doesn't look like much, and you can't see the depth of the blue foam from the photos. Theres a lot more variation in terms of thickness of the foam than you can see. Once the spray foam is cured, I'm going to carve/sand it to give it even more depth and curvature. I got the concrete mix, acrylic fortifier and colorant today. I decided to mix the buff and charcoal colors together to get a dark brown. Hopefully I'll start applying the concrete late tonight. I've still got to install the pieces that go on the ends and the "box" column that will hide the overflow pipe and pump. Ran out of spray foam
After the background, I have to plumb the filters and build the undergravel jet system. So far it's going to be a 3500gph (approx 3000gph after head hight loss) running the filters, and a 2500gph running the undergravel jet. I've got a cool idea for the substrate and undergravel jet (not sand) but I'll wait til I have pics to discuss that.
