DIY overflow box

[Cryptocaryon]

Hi all I decided to make an overflow box based on the exotic marine system model. Was a fun and cheap build.

Interesting! Are you willing to share more details on how you put it together and maybe more pictures from different angles?

Did you drill the tank or was it already drilled? Did you model the project at the Exotic Marine 20" box?

On a separate note, I'm not sure what I'm looking at with the hose. It looks like it is your return hose from the sump and that is is directed into the corner of the tank with no fitting on the end - am I seeing that correctly?

Hey, be glad to share. So I used one sheet of 600x600mm at 5mm thickness to create all parts needed. I draw it out on a piece of paper beforehand just to be sure I could get all the pieces out of one sheet. I needed to drill two holes into glass with a diamond tipped hole cutter for the bulkheads (first time doing this but easy enough if not a little scary) just make sure the tank is not tempered glass, did this by using polorised glasses. I glued the parts together using an acrylic weld solution and to be extra safe of any small leaks I used CT-1 along the internal joints. The pipe you see is a return from the sump. Hope this helps

Nice work! I’ve drilled many tanks, but never built my own overflow. Thanks for sharing!

Any specific recommendations on where to get the acrylic and how to cut it with that precision?

I managed to get hold of everything on Ebay. I cut the acrylic with a jigsaw using a straight edge clamped slightly back from the intended cut line to I could run the jigsaw in a straight line. However this did have its shortcomings and lots of sanding was needed after the cut. If I were to do this again I would not use a jigsaw. There are companys that will cut the acrylic to size for you, Unless of course you have a nice big table band saw then go for it.
