Tank Rim Cracked

[Alexp08]

So i just bought a 29gal (30x12x18) quarantine tank. I got it home and was cleaning it and noticed that the top black rim has a crack in it. It is all the way through. How big of problem is this, and is there anyway to fix it / rig it to work?
 

 
The is not a crack in the glass, its cat hair lol

Not a problem at all, it may let some water out from splashing so i would take some aquarium silicone (100% silicone) and scrape it over the crack and let it dry, then you  should be good. Its what ive done to a 55, 75, and 180 gallon fish tank...

Really not a problem? I wouldnt expect this. I thought the point of the rim was to keep the glass together and keep it from busting apart.

The plastic is siliconed all the way around, so a lil crack like that doesnt break any bonds, and the glass itself is siliconed together, the plastic trim i would say is more for protection from other objects. You will do fine with just putting some more silicone in the crack.

I had a tank that was missing the bottom pieces of plastic on both short sides of the tank.  It ran for a long time and never had an issues.  While this isn't advisable, I'm just throwing it out there.
 
I think yours will be fine.  Like sawickib said, you can fill it in with aquarium silicone for peace of mind and to prevent any water dripping down the cracked portion

I was thinking something along the lines of JB weld, or in this case is silicone stronger?

 

[sawickib]

Its not a matter of strength, its more so toxicity of the substance, 100% clear silicone doesnt leak anything when dry into the water, it is also just being used to seal the crack, but just remember your entire tank is held together by 100% silicone so it will be completely find!
