crazing and bowing, risk of rupture?

  • We are currently upgrading MFK. thanks! -neo
Then the last thing you need is a tank of that size failing.

As aldiaz stated its very rare for a complete panel to pop out unless the tank was built using the wrong glue/acrylic.

Very true, chances are if there is going to be a failure it will be in the form of a seam failing, but that could still result in 400 gallons of water on the owners floor. That said, for a starter I would ensure that all electrical in that room is running off of a GFCI circuit or breaker. If the tank does fail or leak, a GFCI could prevent electrical shock, or worse. Good luck.
 
X2 on gluing acrylic strips into the inside corners.
Drain the tank clean all the inside corners good. Get some 1/2x1/2 square stock and glue them all in with weld on 40

If the effort is made to drain and reinforce, it may be worth applying an acrylic 3-4" width 1" thick bracing around the entire top and bottom perimeter. Similar to eurobracing on glass tanks. I dont think the bracing would look bad either if done right. I've not done this but have seen it done and food for thought.

Advanced Acrylics is going to help us build a new aquarium just like ours! I'm so happy about this! We got our beautiful custom sump from them last year.

I have been feeling hesitant to reinforce this tank myself. It will still have excessive crazing and might always bow unless reinforced across the middle. I feel a lot more comfortable getting a new tank.

Thank you so much everyone for your advise and comments.

This is an interesting idea. Maybe a new canopy and stand could be designed to cover over the bracing.

I've decided to get a new tank. It will take awhile to save but I feel it will be the best option for us. Advanced Acrylics is giving us an amazing deal and letting me make payments too. I'm very grateful.
 
^ its good to hear you managed to work something out for the long run, seems you definitely could do without the hassle of a leaking tank...

good choice, while everyone has differing opinions; and some like myself haven't kept acrylic tanks (of that size), I'd like to think safety would be everyone's top concern...plus as stated elsewhere, your existing tank is worth a lot of money; you could ideally offset a lot of the cost of your new tank by selling it to someone that knows what to do with it.

Hi Aldiaz33. Tank is holding up great.

I have no plans to purchase a new tank at this point. We had some financial setbacks and had to put off purchasing a new tank. Now I am not so certain it is a danger. I contacted 4 major tank manufacturers, 3 of which wanted to sell me a tank that is the same thickness acrylic or thinner. I don't trust that a new tank would not also bow and craze. We don't sit directly in front of the tank.

I actually worry more about radiation from the pumps/jets. I purchased a trifield radiation meter because we recently had a smart meter and solar inverters mounted right outside our bedroom where we sleep at night and the magnetic radiation levels concerned me. I found out the aquariums produce a lot more radiation than the solar inverters and smart meter. I should make a video to show how bad it is. It is good to stand 3+ feet back from your aquarium pumps to avoid radiation.
 
^ hmmm i want to do some research on this and hear more, but its late and im about to sleep...

But where and what sort of radition is coming from the pumps? And by pumps you mean Air Pumps?
