Chipped corner

[JDJP]

Thinking of buying this tank. Its 300gallon, a marineland i believe. Has a pretty bad chip in the corner.

Any way to repair this? I was thinking fill it with clear epoxy and maybe silicone a triangle shaped rod of glass or acrylic on the inside to fill the corner? Im guessing most of you wouldnt trust it?

I wouldn't have it inside my house. It would be outside or in garage in the future.

I wouldn’t... 300 gallons is too must spillage to risk!

I would not use that tank. Chip has fracture lines off of it. Most likely it would fail catastrophically.

Replace the sheet, only way I would be comfortable setting it up.

I haven't seen it in person, but where do you see fracture lines?

This looks like the same tank someone else asked about on here just days ago. There is no way to repair it, other than replacing the glass panel. Plus, I don't know how old the tank is, but I believe Marineland had an issue with some of the large tanks rupturing in the past. Personally, I would steer way away from that tank. Not worth the potential serious issues down the road - to the tank, the tank's inhabitants and your home.

You could also get another panel to fit inside the tank and silicone it to the current panel. It would give you the stability you would need. The downfall would be that side would have to be painted as it wouldn’t look so good from the side haha.

I wouldn't trust it either. Depending on where you live at you are likely able to purchase a replacement panel from a local glass shop for less than a new tank. You can even have them put a slight bevel on the outer vertical edges as well. If you do decide to replace it you will need a box cutter, clear 100% silicone, and one of those caulking tool kits.

The hard part will be removing the top and bottom trim panels but with the box cutter and a little finesse they will come off. After that you will want to cut seam on the damaged panel to remove it. The old silicone on the remaining panels will need to be completely removed and cleaned with a residue free cleaning agent like denatured alcohol. Next step is applying new silicone on the tank and carefully placing the new panel on the tank (may take two people). Then you will need to use the caulk tool to carefully spread the silicone and recreate the seam seal making sure to extend past the bottom to the un-touched silicone to ensure the seal restored. The tank will need to be left for at least 24-48 hours for the silicone to fully cure. If the trim panels have a center brace they will need to be reinstalled prior to filling the tank for leak testing. When you do get to this phase make sure the tank is absolutely level as the torsional stress can and will cause leaks. Once filled I would leave it that way for at least 2-3 days just to be sure there are no issues. The last thing you want is to fill get it set back up only to have it to have a slow seep that may not have been noticeable if you filled it left it sit for 20-30 min than drained it.

There are plenty of videos on doing this on YouTube.

Good luck.
