Travelling Frag Tank

I have been scouring eBay, BRS,, and all over the internet for the perfect frag tank (for me), and couldn’t find exactly what I wanted.
There were plenty of acrylic tanks that were close but the footprint didn’t match what I was looking for at the height I was after. I inquired about custom building to my dimensions then the cost was much more. So rather than settle for almost the right size I decided to build my own, thinking it would be fun and probably save a few bucks.

Well the saving a few bucks part went out the window, but after a lot of scratching my head, punching on a calculator, and pestering the poor woman at the glass company, I finally decided on the exact size, types of glass, and stepped into another project, because I don’t have enough projects …

I will update this as I go but for now the glass has arrived.


Yessssss! This is gonna be awesome!

Years ago I built my own frag tank with acrylic and was fun to do.
looking forward to see the progress you make on this DIY project :+1:

I agree this looks awesome!! What are dimensions of the tank you are building?

The footprint is 24x20

It will have an overflow in the rear at 4” wide

That gives me about 23 1/2” long left to right and 16” front to back at 8” deep

This will hold 6 square frag racks that are about 7 1/2” square

The bottom glass and overflow divider are dark grey (almost black) the rest is standard green edged glass

In planning to take the bottom frame off of a 10 gallon tank and cut it up to fashion four “feet” at each corner to keep it off of the table/stand

Going to use black silicone to put it all together

Can’t wait to see how it turns out!

Started piecing the tank together today:

I started with the divider that separates the display from the filtration/media area ( I needed to get the baffles securely in place before moving forward, they are suspended and I couldn’t think of a good way to do that without letting them set a few hours ahead of the rest.

P.S. I actually took one of the baffles (center one) back to Kennett Glass to be shortened. I overlooked the height of the baffle being the same height as the bottom of the overflow. I didn’t think the water would flow well through the baffles this way so I took an inch off of the center one.

Once the baffles were set up and curing for about two hours I set two adjacent sides in place before installing the divider with baffles.

I figured it would be easier to do this before setting up all four sides.

Prior to setting the sides I put tape under the bottom glass to use as stableizers as each piece goes up. Once the corners were squared up I used additional tape to keep them from sliding out of position.

In hind sight I would have positioned the rear panel first followed by the divider with baffles, then the side, but it turned out ok.

The last two sides went pretty easily, now I am waiting for it to fully cure before attempting to move it.
I decided to wait until all of this set up and cured before putting the inside bead around all of the corners. If this was a permanent tank and didn’t have the complexity of the baffles I would have done this as I went. I am confident that I have a good seal on all of the joints and I will water test it before putting the final bead in place.

I am happy with the results so far.


I went ahead and put the bulkhead in place and loosely set up the return hardware just to see what it would look like.

I think I will only use about half of the length of flex joints that I purchased.

Looks like I will have plenty of room to put a heater, pump, and media basket for filtration.


Looking good, nice job!!!

How heavy will it be when finished?

I’m not sure, that’s a good question. It doesn’t seem like it’s gonna be too bad.

It shouldn’t be much worse than the 20 gallon long I used to lug around

Thanks John it’s a fun project. I dred smoothing out the silicone, Im not good at it

That is really impressive and looks sharp! Can’t wait to see it in action.

The tank is weighing in at 29 pounds, a little heavier than I thought it would be.
