Acrylic, silicone and a router.

Without a router you're going to be drilling a lot of holes and cutting/sanding to get the same look. Essentially just drawing out your shape on a piece of thick acrylic and then drilling a similar sized hole over and over to get the majority of the material out. Then cutting and sanding to smooth it out and remove the remainder.

I'll give it a shot. What do i do for the black acrylic?

Was looking online for "plans" but have had a hard time finding any. Essentially map out the space you want to have as your overflow with the space for exit and return bulkheads. Once you have the measurements (length and height of the individual pieces), you need to get some acrylic. Black acrylic seems to be a favorite. You can buy this online. I would use something around 1/4 an inch thick.

Once receiving, you need to cut the acrylic down to size into rectangles that would fit together to form the dimensions you were looking for. Draw out the fins along the top, more or less, the water flow will differ. Most fins tend to be roughly less than 1/4 an inch. drill out holes roughly this size and then sand/cut out the rest.

Silicone together and in place. Just a warning, after making my own sump, acrylic does not bond well to glass. You have to use quite a bit of silicone. Might not look pristine, but it does work.

Here is a link specified to helping people with acrylic fabrication. Im sure they would have a little more of an informative answer!

Are u doing acrylic to glass?

The tank is going to be glass, but i'm going to use acrylic for the overflow

you can order black acrylic off ebay, you will want some weld-on 16 or 4 to glue the acrylic box then use silicon to attach it to the glass tank.
