I have in my possesion, a 95 gal saltwater tank that has a small crack in the bottom. Is there anyway to fix tank?

Nope, not if you want to sleep at night.
A new 95g is under 200 bucks. certainly nothing to just throw away money wise. But killing all your livestock not to mentiion your homes floors can be thousands very quickly.
I should ask how large the crack is and which way it runs along with other details, but honestly I wouldnt do it if it was anythig beyond a small chip. Just too much risk.
Might post the tank on your local craigslist and then use the proceeds to offset the new tank that you can rely on and sleep at ease at night.

I agree. If it is a crack that runs all the way through (you can feel it on both sides of the glass) it is almost certain that sooner or later you will have problems, if not catastrophic failure as soon as you fill it with water. The thing is that any tank bigger than about 20gal is designed to have a certain (and demonstrable) level of "give" (bowing) in the glass. Placing a perfectly straight edge across the front of a full tank will show you just how much it really is. My 120g FW tank's glass bows out almost 1/4" in the middle of the front.
That torsion pressure on a crack will cause it to spread very easily.
If the crack doesn't go all the way through, it's possible that it will hold, but the integrity of the glass is compromised so failure is much more likely. 95 gallons of water, seawater to boot, will make a really bad and expensive mess.
Sell the tank in your classifeds or Craigslist to someone who keeps reptiles, and kick that money back into a new tank.

I just bought a new bowfront a couple weeks ago, and during the leak test a small crack developed in the corner of the bottom plate. The store that I bought it from is 100 miles away, so if I can just pay a local glass shop to fix the bottom, I'd be more tempted to go that way than to return it. Are the only decent options for a tank with a cracked bottom to throw it away or use it for reptiles? They're considered unrepairable?

I'm not sure the cost of the repair will make it worthwhile.

I see the concern with the $, but I wouldn't even start to risk it. I would be so worried that a crash could happen. I've read sooooo many horror stories here on SWF to risk a small crack. I agree, a 95 is less than $200. $200 is a bit, but will seem like nothing once the tank is on the floor.
