Hello everyone,
Im stuck in a bad situation and not sure what the best solution is so I figured I would come here to ask for different opinions. I have a 230 gallon tank I purchased years ago, it was a marinland (perfecto) brand. I built this tank into the center of my living room into what was originally a closet, I built stone around everything and spent a lot f time and energy on. After having the tank for 4 years it sprang a small leak in the middle of the backside wich was caused by apparently bad sealing. I came home one day to find 60 gallons gone from the tank and into my hardwood floor. I quickly rushed to save my fish wich was most important and had to deal with the damage and remove all remaining water and props that were inside...Without getting into all the detail, I settled with marineland, they reimbursed me with a fraction of the cost, but now I am left with this huge tank that is empty and I would love to do something with it. The hard water has caused a fog that I cant seem to remove as I thought about doing a terrarium or something without too much water within it, but the glass has a lot of imperfections you notice without water filled. I cant seem to remove the imperfections after trying every solution possible. My question to this forum would be, is it possible to reseal the bottom seals without taking the tank out? (maybe climbing inside it and sealing it?). Is there something I can pour into it so the bottom totally seals? Can I spray flex seal in it possibly? Is there any option to possible make this tank able to fill up with water again without removing this big tank and everything around it? Any help would be greatly appreciated thank you !

You might be able to get away with removing the silicone fillet from around the bottom of the tank and then replace it, Assuming that's where the leak is. But, I don't know if I'd really trust that. Can you not remove the tank without disassembling it?

Masking off all the edges and giving it a good coating of pond paint might work. Might look kind of interesting, like a picture frame effect similar to black silicone. But I still wouldn't trust that much either.

yes unfortunately I cannot remove the tank without taking the wall apart and causing a lot of extra work to build it back...I would consider possibly just buying another tank same dimensions if it was easy to remove and put back but im stuck in a bad situation. I do believe the leak is in the bottom part of the sealing.
 
Not what you want to hear I'm sure, but the problem with big glass tanks like this 230g one is once they leak then really the only way to fix it is to actually take the whole tank itself apart and reseal not just the inner fillet seal, but the butt seals between each panel as well. I found that out myself the hard way about 7 yrs ago when I had a 7ft 265g tank that leaked. I redid the fillet seal after it leaked, and it started leaking about 3 weeks later. I redid it a 2nd time, and it leaked again about a month later. And I am a VERY OCD person so when I resealed it I did it 100% the the best job possible, cleaned it like you would not believe before applying the strongest silicone I could get (1800 something or other it was called) and yet it still leaked. There's just so much water pressure at the bottom of these bigger tank that once the butt joint has an issue then just redoing the fillet seal won't last very long.
