Hello; I will assume that you are refering to the plastic trim that goes around the perimeter of the bottom. While i have not foxed a tank as large as a 230 gallon, I have fixed smaller plastic rims. The most recent was when the bottom trim came lose. It was fairly simple to put it back with a good line of silicone.

I would go about your issue in a different way. First try to determine if the glass was affected by whatever cracked the trim. If the glass seems OK, then I would likely patch the crack with a two part epoxy. There are different types of epoxy. Some cure very hard and others are more flexable when cured. I would go with a more flexable type, read ther label. If you have not used epoxy, it might be good to practice with it a bit.

You might also do a search of this forum. This issue has been posted before.

good luck

Thankyou for your response, unfortunately it is not the trim. The glass base is cracked and extends across the tank. Being in Australia any thing aquarium related can get very expensive hense looking for a cheap repair. I am considering have 12mm glass panel cut and sliding inside of tank on top of cracked base.

Hello; The bottom pane of glass is cracked? I have repaired smaller tanks with glass cracks. I got a piece of glass that covered well beyond the crack on the inside. Not just a few inches, but a good distance. It may also be possible to put a second patch panel on the outside. I siliconed it in place. This has worked a few times for me. A line of silicone right along the crack and plenty of silicone under the rest of the repair pane. It is pretty much a one shot placement so get the patch pane the right size and test fit it before using the silicone. Have everything clean and dry. No little bits of glass or other grit.

With any such repair there is a chance of problems. I would test fill it someplace where a leak or sudden failure won't do water damage. I would also leave the test fill for as long as you can stand. Some such patches have held for a long time while others leaked right away.

good luck

That is a dangerous game to play, especially with a tank this big. You really need to take the tank apart fully and rebuild. A patch is not the route to go in this situation. Also 12mm is not nearly thick enough. You should be looking more in the 19mm range.

Once upon a time there was 2,000lbs of water....The End.

I make light just to be cheeky and I mean no disrespect....simply put, and it was said before, take the tank apart and replace the glass.
...or....
Disassemble the tank and use the glass for a plywood build.....
Don't lose hope...it can be repaired with the proper work/glass, but given the money involved you might consider selling the tank to a reptile guy and get yourself a safer project...like a scratched up acrylic tank...people get rid of those because they think the tank.is ruined by scratches.

Hello; Allow me to join the chorus of doing a patch is not a particuraly safe idea. You asked if it can be done. Yes, but it would be a constant worry of failure to me. It may work, but the volume of water is a concern. As a basement tank or garage tank with a floor drain would be where I might take a chance, not in a house room.

^ no offense, but even then I personally wouldnt risk it in fear of losimg any prized fish i had in there...

And knowing what prices for fish in Australia is like, the last thing you want to replace is your tank / fish and part of the house...

I think honestly owning a dog would possibly be cheaper than keeping fish in Australia...
