how not to repair a large tank with cracked glass
 

im sorry i may be a cheap bugger but even i think this is rediculously stupid you spent how much for a custom tank and you cant fix it properly dude you may as well have just used duct tape

he said it was second hand...

and i think thats not to bad of a fix - silicone is what holds the tank together not the glass. ive filled a cracked 120g all the way without even sealing it with silicon and it never leaked or broke in over a year. the crack was 5 inches long in breaking the corner of the tank.

lol - i only did that because i didnt care if it exploded it being in a concrete basment i flooded enough times already.

1600g of water and he hopes it will hold.... i dunno i think it needed better bracing and definately a newfront pane of glass no point in filling it if you are going to look at a crack all day.

yes i know he said no one wanted to replace it but it said that it cost him 60 euros or pounds to repair as he did and would have cost him 200 euros or pounds to replace the glass, i guess if hes happy. who am i to critic his work i just would have saved and made it stronger and replaced the glass.. thats just me

I agree and think thats completely idiotic. It will fail. Maybe not today or tomorrow... but someday. I have built many tanks and used to work at a tank manufacturing wharehouse.

The glass gets flexed all the way across and supports itself end to end. There is nothing between the cracks to minimize the bowing that IS stress on the glass.

I would never do that. I hope things work out for him.

(even if one was going to do a 'fix' that way... I dont think the bracing they used is at all adequate.)

1600 Litres not Gallons, just saying.

it was late i stand corrected lol but even so i still say epic fail

every piece of glass on that tank seems too thin to me to begin with. i'd put money on that thing failing someday soon.

I'm confused
 

So, his large 12mm glass cracked on the side of the tank, and the "fix" is to silicone (badly) a large peice of 6mm over the crack on the inside?


Think about this for a moment:

1) half the thinkness for a know stress location.
2) he doesn't seem to understand how silcone holds on glass, adding beads doesn't do much
2) the inside?

Remember that the water is pushing out from the inside, imagine 2 2x4's held together by a bit of cardboard and then puch from the 2x4 side. It won't bend much.
Now push from the cardboard side and the whole thing folds up.......

I'd be really, really, really suprised if this thing holds water long enough to get it filled. Yikes!

automatic floor washer fill up goooosh floor clean

Buddy only paid 500 pounds for it, why not do it right and replace the glass? Anyone ever see the show Disaster DIY? This would make one hell of an episode.

But he is going to turn it around and put some polystyrene over it! Kinda like putting lipstick on a pig if you ask me, I would never put that in my house.

very ugly, and quite the eye sore now. No exotic fish will take away the ugliness of the tank now. Time for a new one.

LOL... *Like* mr. fish's comment.


or 1 time use wavebox?:lol:

I commented on you tube and he sent one right back within minutes. Apparently the tank's been running for over a year with no issues. If it was me, I don't think I'd be able to sleep at night.

he is lucky its lasted a year and im quite surprised at that to be honest. but a patch is a patch and is still weak in the area. hell im nervouse repairingmy 180 with a whole new piece what if the seal pops on that. or i dont seal it properly. so far i have done well with rebuilding tanks. but nothing over 50g. pray for me lol
