Make all cut very accurate for best results. Within .5 or 1mm then sand and scrape or else use a quality flat edge router to smooth edge's perfectly flat before gluing together. Use #4 Acrylic Cement to connect piece's. This cement makes the two piece's of acrylic a single piece. Since there is no gap filling with this the edge's need to be smooth, then cement applied with a fine needle tip bottle. This melts the acrylic letting you join the piece's together. Use a stretchy tape like electrical tape while connecting or use consistant pressure on the piece while it dries. Acrylic can be cut with fine tooth high count table saw blades. Use a minimum 100 tooth blade with flat top's (no offset teeth). Smooth edge's and flat top blade is recommended for the best cut. High speed of at least 4800 rpm (5200+ recommended) with 100+ tooth blade will give a perfect cut.
Example of an offset saw blade (not recommended). You will have to do more sanding and possible get chips in your acrylic if you use "OFFSET" blades.
Example of a flat edge Acrylic Saw Blade Tip (recommended). Most high count 100+ saw blades will cut acrylic just fine.
Jigsaw can be used for difficult cuts at home, use styrofoam sheets the thickness of your blade under the piece's of acrylic while cutting with a jigsaw. This prevents bending and cracking by spreading it's weight on the foam.  
Marking and Cutting Instructions with Diagrams how to build an all-in-one acrylic fish tank.
1. get (2) 1/4" or 3/8" thick acrylic sheets or equivalent 2' x 4', For example: go to menards or mac's hardware and get (2) 2' x 4' sheets of acrylic if in town (these sheets are usually .22" and have blue covering on it). Otherwise order sheets from an online store and buy CELL CAST ACRYLIC SHEETS that are 1/4" (.25") thick, or 3/8" .375" thick.
2. make any size you want but for the standard 2' model use these measurements, for smaller or larger replace with your own. Use .22", .25", or .375 (3/8") thick acrylic sheet with these instructions.
3. mark with a marker or sharpie these measurements on the sheets for the cuts you will do later.  (ONLY IF you measure the thickness of the saw blade, otherwise "MEASURE/CUT/MEASURE/CUT exc.)
4. Mark Sheet 1 at 16" in and cut making a 16" x 24" piece. This is 1st cut on Sheet 1.
Sheet 1
5. take the left-over from step 4 and make another cut 16" in making Piece 2. Now you have two 16" x 24" (Pieces 1 and 2). This is 2nd cut on Sheet 1. These will be the large front and back pieces.
6. take sheet 2 and mark it at 10 1/4" for Model A, 9 3/4" for Model B. This is Cut 1 on Sheet 2 making Piece 3. This will be the top piece 24" x A,B.
Sheet 2

7. take Sheet 2 and mark it at 10 1/4" for Model A, 9 3/4" for Model B. This is Cut 2 on Sheet 2 making Piece 4. (either AFTER cutting Piece 3 or measuring saw blade and marking each piece)

8. take Sheet 2 and mark it at 10 1/4"A, 9 3/4"B. This is Cut 3 on Sheet 2 making Piece 5. (either AFTER cutting Piece 4 or measuring saw blade)
9. take Piece 3 and mark it at 23 1/2 for 1/4" thick acrylic sheet. For example mark at 23.6 for .22" acrylic sheet (cheap acrylic sheet found at hardware stores), or mark at 23.25" for 3/8" acrylic sheet. This will be the top piece.
Piece 3
10. take Piece 4 and mark it at 15 3/4" for 1/4" acrylic sheet. For example mark at 15.6 for .22" acrylic sheet, or mark at 15 5/8" for 3/8" acrylic sheet. This is Cut 1 on Piece 4.
11. take Piece 5 and mark it the same as step 10 and make cut 1. (10 3/4" for 1/4" acrylic sheet). You now have two pieces of your own side depending on if you're making a Model A or B, and the thickness of acrylic you're using. These will be the side pieces.
12. take the left-over from Piece 4 and mark it at 4". Make Cut 1 Making Piece 6.
13. take the left-over from step 12 and mark it at 4", make Cut 2 making Piece 7. Now you have two piece's either 4" x (10 1/4"A, or 9 3/4"B) These will be the middle side piece.
14. take the left-over from Piece 5 and mark it at 6 1/5" for 1/4" acrylic sheet. Making Piece 8. Now you have one piece either 6.5" x (10 1/4"A, or 9 3/4"B). This will be the middle span piece.  
15. take Piece 1 and 2 and cut out the bottom center for the gap. This will be 4" up and 6" center gap. Use a jigsaw with foam under piece's as thick as your jigsaw blade is long, or use equivalent method to cut this piece out. Use example Cuts if you're using a jigsaw.
You now have all of the piece's cut out to make the All-in-One Aquarium. You will see the measurements should incorporate the thickness of matarerial used. Follow this description to fit the piece's together.
Glue AFTER smoothing the blade cuts and TEST FITTING with a few piece's of tape and seeing it will fit together.  Use correct Acrylic Cement and REINFORCING STRIPS (If needed).
16. Cement Piece's together. I recommend taping all of the outside piece's only first. Then Gluing like a regular tank. Then once the tank is together you can glue in the last three middle piece's in.

17. Tape outside piece's together so it resemble's a regular fish tank. Flip upside down so gravity is always pulling the acrylic cement down into the seam. If you notice bubbles right away put more tape or apply pressure while it dries. 
18. Keep rotating the tank giving about 2-4 minutes for the cement to "set" before moving and gluing the sides.
19. Test Fit the three center piece's by taping, then either take it apart and Cement the three middle piece's together one at a time, or glue it while taped in the tank. Make sure they are set at 90 degrees so that they will fit your tank.
20. Allow to dry for 24 hours per 1/4 inch thick acrylic, add 12 hours per 1/8 inch on top of that.
Once all these piece's are cemented together and dry you HAVE A NEW DIY ALL-IN-ONE AQUARIUM!!  You can build multiple's and connect them together using our different size options, or just connect your tanks together.
Set up as a regular fish tank or terrarium as it is, or connect between tanks as a terrarium. Use a DIY vacuum pump to raise water level between tanks. Convert your Aquarium Air Pump to suck the air out and connect your two fish tanks or expand your large tank. See Video's how to fill with this method.
21. Either Buy a Vacuum Pump, or build one yourself with our DIY Vacuum Pump Instructions.  Make a Floater Assembly for the DIY air pump, or make a DIY Sensor Assembly for a Completely automatic water level system.
