Tank Build! Up-sizing our tank to a 265 display!

I've never done a build thread from the start of a project, so I figured this was the perfect time to do so. We found a deal we couldn't pass up on a used 265g Marineland with corner overflows which was just a foot longer than the 220g we were looking at getting. My wife has been awesome and she's just as excited! This will probably take us a while to finish and most likely will have changes along the way. If anything, this thread will help us keep track of changes and ideas if anyone has better ones than ours.

Progress thus far:

Basement FISH ROOM!
Knocked out a wall in the basement to create a 24ft x 8 ft. Currently looking at framing, closed-cell foam insulating exterior walls, and putting up mold resistant drywall with painted finish. Also planning to install a dual exhaust fan attached to a humidistat connected to my Apex. Probably going to install a fresh air line with carbon filter for the skimmer. There will be a utility sink with working bench style space for working on corals, etc. Also planning to install R/O and saltwater storage tanks for easy (hopefully automated) water changes. There will be a fish and coral quarantine tanks setup to reduce risk of disease and pests.

The Display (265g)
For those that have seen our current 125g setup, it's view-able on both long sides with one in a window like cutout that faces our kitchen. Will also be able to view this new tank on the right shorter side. The 265 will be in the same space with another diy stand, and since all the filtration will be in the basement, I plan on making some storage drawer into the stand to hide away things we need for the display so that we don't have to run downstairs for those items.

Currently I am thinking I want to replace/freshen up 2 of the interior silicon seals as they show a bit a wear from the assumed cleaning/scraping of the glass. I've never done this type of seam on a tank, just bathroom/window seals. Any suggestions from anyone that has done this before? Should I do it at all since it's not really the structural seam?

Thanks to everyone and we look forward to sharing our journey with the club!
Pictures to come soon.

This is how the tank looked when we got it 3 sides painted.

This is progress made

This is a mockup that we built to compare and use for moving practice. The wood on the left is the exact size of the tank if it was skinned, the 125g is the current tank.

 

Let me know if you want to check it out in person. House is all torn apart with Christmas decorations and now tank projects, but you'll get the idea.
This tank is bigger in all directions. 7ft x 2ft x 30 inches

 

Do you have any personal experience with either? I'm still trying to figure out what to run.

 

With all of our plants and the current tank, we were fighting humidity this year badly. We picked up a decent dehumidifier until I get things moved to the basement.

 

I will have to admit that progress has been reaaaallllly slow due to me being sick for the last month. I just got my R/O setup moved to the basement which was the first step.

 

Hey all! The updates are that there currently aren't any updates . With the Covid-19, I've been working a lot more and haven't had any time to work on the tank, not that I could get all the requirement plumbing supplies now anyways.

I would like to know, who has a large Rubbermaid style tank (100+ gal) that they are using for a sump? I'm looking at creating divide sections using cut glass or acrylic , but I haven't quite settled on the design. My holdup has been getting glass cut to fit the curved features inside the Rubbermaid, any ideas?

I'd like the sump to include:
-Middle return section (small enough that I can use an ATO sensor in it that it's not waiting for gallons of evap. before running due to the surface area)
-Section for filter socks on the Drains
-Bubble traps going from drain into Skimmer section
-Skimmer chamber where water level is consistent
-Possibly a fuge area ( might setup an independent tank for this

I'll take all ideas, pictures, etc. Let's see those sumps!
