Hey everyone,

This is going to be my build thread for my very own AIO creation. To start, I bought this 48x20x12 aquarium brand new today and it came predrilled with a plugged bulkhead (that I won't be using at this time). I have chosen to go this route due to the lack of space below where I intend to put this tank when I move at the end of July (beefy custom built in shelving unit in a wall at my next home).

I have ordered black acrylic online that should be here this week so I can form my sump section in the back. I will be creating a 12" wide and 4" deep sump in the back right corner out of the acrylic I have on order. This will be a simple set up, allowing space for a filter sock, my heaters, temp prone to my apex system, and my return pump to be hidden within the tank.

I'm a pretty low tech guy, and just do religious water changes (10% weekly). None of my equipment is very fancy with exception to the apex system. I will be using 2 Chinese black box led systems that you find on eBay (have been using one on another system for the last 2 years without issue), a jebao pp-8 wavemaker (I have supplemental powerheads I can use if necessary), a couple tetra brand heaters, rectangular innovative marine mid size filter socks with the built on holders, and a 264 gph pacific hydrostar submersible fountain pump I used on a previous tank that has since been consolidated. I'm assuming this pump will give me about the 5x turnover rate I want to run through my internal sump since the tank is going to have an actual 40 gallons or so of water in it by the time rock, corals, and the sump are all in taking up space.

I cannot wait to see how this build progresses, and I hope you guys enjoy the journey as well!

Here is the tank when I went to get it. You can see the pre drilled hole in the back right corner, the store owner threw in the bulkhead for free since I told him my plan and let him know I wasn't looking for pre drilled.
 
I couldn't wait to start thinking about my aquascape so I mocked up the sump and made a couple little temporary cardboard towers to set the height to imagine how I'm gonna start placing a waterfall effect of some little shelves going down and around the corner sump. Will probably add a 4th tier directly on the glass. I am going to make this tank bare bottom I've decided. I will probably have to make some thin, yet realistic looking rock towers out of smaller rocks and rock glue/putty to support the shelves when the time comes. Unless I figure out a way to hide an acrylic shelf around the overflow attacked to the side and back of the tank to give the shelves a floating appearance that is![emoji12] I am still to decide what to do with the left half of the tank, likely an island or arch feature that will still leave plenty of swimming room for my fish fam.

Got the filter socks in today! Acrylic should be here in the next couple days so I can build my sump section.

Got the acrylic in the mail early today! Came as a 12x24 sheet, I cut it into these 4x12 strips and the 12x12 square to build the sump section in the corner. Was nerve wracking because I have never cut acrylic with a plastic cutting knife before and I didn't want to break the pieces wrong when it came time to snap them at the line. Luckily no breaks went awry so the sheet was the perfect amount of acrylic for $12 on eBay :) time to drill all the holes to make them functional as baffles and as an overflow weir on the main square piece!

Almost done setting enough so I can silicone it to the tank! As you can see, I decided to make the baffles shorter rather than drilling holes into them, I'm gonna use the 2" x 4" strips of acrylic I cut from the baffles to try to suspend those waterfall rocks on the sump wall. [emoji51]
 
Hey Everyone! Sorry I have been away for a while, did a little traveling and work caught up with me. I will be posting an update soon! The DIY sump is siliconed into the tank and I am doing leak testing as I type this! Pictures Coming Soon!
 
Where is this tank at? Seems like a cool build!
 
Nice work. Keep us updated. :)
