Fishkeeper's Worst Nightmares?

It's scary having that happen to you, it's always been a reoccurring thought in the back of my head but I thought I was just being paranoid.
Like I said it could have been waaay worse than it was and I'm just thankful that I was home when it happened and that it wasn't a complete catastrophe lol

So you used aquarium seal to fix a crack or something? And after time it gave way?

No my grandpa must have fixed the seals at one point when he had it and I just never thought to ask if it was usable

 

Wow, you must be so glad you were there and managed to save the fish. Do you have any idea what contributed to the tank breaking?
Edit - sorry cross-posted with previous messages.

My grandfather re-sealed it when he still had it he forgot about it and about 5 yrs ago I needed a tank and he gave me the re-sealed one without realizing it, and so 5 yrs later it comes undone and that is where I'm at lol



its coming together, it's crowded and it doesn't look good right now but when I get home from work it's getting rearranged, I just wanted to get the hidey holes in there so nobody is stressed out too much

 

Ah I see. I still wouldn't expect a resealed tank to come apart though. How scary. Good work on the fish rescue!

 

Right now it's a mixed community tank and there's nothing I can do about that for now, every fish has and is getting along very well and if they're doing great together then why bother them. But just so nobody gets tense about the setup mixed species tank I am going to be bringing certain fish back once I see any signs of aggressive behavior, but right now I've spent nearly 2 grand this past month alone buying fish and getting everything I needed to startup my aquarium just to have it collapse. So buying another tank to separate everyone is not an option at all right now, the way I look at this situation is if everybody gets along in one big tank that's perfectly fine with me if they live together for the time being.

 

Hello, your tank stand doesn't seem to be covering the tank bottom could this be an issue or cause? Just asking cause I'm getting ready to setup used 55 gal. too. Thanks!

It's hanging over half an inch on the right side but other than that it's on the stand not hanging over anywhere else

 

Hello again, from what I understand a gal.of water is 8.34 lbs. so total weight of 55gal. tank filled is 625lbs. a little tweak could cause a lot of stress.
Hope this helps !

Hello again again, sorry for sounding like a (know it all). I was actually researching this info. last night trying to decide if I should use my 55 & thought I should share. Thanks!

 

Everyone in the setup is doing great together I'm hoping that doesn't change.

 

I've read it's very important to make sure you have the entire bottom surface in contact with the stand or whatever the tank is on and make sure it's level. Over time, the tank will settle and start to twist causing lots of stress on the seals. King of DIY on youtube explains it on his video about leveling a tank. Hope this helps!

 

Having the tank level is more of an aesthetic thing, trying to level a tank can make it more appealing to the eye but structurally worse if it doesn't stay true. It is technically correct that if it is out of level that slightly more pressure is exerted on one pane than the rest, however, twisting the seals is far more dangerous. Having it supported fully and true is very important. If the last tank hung over the sides the way this one does it definitely contributed to it pulling apart.

 

Yeah, I wouldn’t feel comfortable with part of the bottom overhanging either. From what little I know, the four corners should definitely be supported.

 

On glass you can get away with only supporting the full front and back, and on narrower tanks, only fully supporting the sides. You can't let them cantilever. Glass is really really strong stuff but you have to play to its strengths and can't ignore its weaknesses. I work in fiber optics a piece of glass only 9 microns wide is sending you this forum post now, that and every phone call txt web page you visit, pretty much everything in society now. The outer cladding is only 125 microns in diameter. Flex it even a little bit to much and it snaps but if you lose that piece it might stab clear through your finger or worse your eye if pressed the right way.
This tank came apart if I read it right, which meant the glass could handle the stress but the old silicone joints couldn't. The panes were stressed and their old joints gave in kind of like mine

 

The other tank was on a different stand that covered the whole bottom of the aquarium, now the deal with the new 55 and what it's being held on. I was not prepared to have a tank bust apart on me nor was I planning on upgrading to a larger newer tank until summer came along, so I was not prepared to have a 55 gallon setup within 2 days without having a proper stand to hold it. The table it's on is solid hardwood and yes unfortunately it's hanging over nearly an inch on one side, nothing I can do about that it had to go on something level and stable and that all I had on hand.
I'm nearly completely broke now since I had to buy a 250 dollar fish tank so buying a stand that's an extra hundred dollars isn't possible right now it will happen but not for awhile this set us back big time.

But that's life, you just gotta pick up the pieces and get back up.

 

Great way of looking at it Life has it's strange ways of keeping us on our toes.

No doubt the glass is strong, seeing how the seal came fully undone on the right back corner and the left front corner came apart halfway the glass never once bowed out or anything, plus after I emptied it out I dropped it by accident and nothing happened no cracks nothing. So in my personal opinion that glass is stronger than people think

 

I personally won't use a glass tank over 40 gallons. An acrylic tank seems really cheap compared to whipping your house out, or your neighbores house that live below you. As mentioned level isn't as important than a flat surface, even though both are important. It sounds like bad prep on the seal job on you old tank. If you can't afford a new stand for your new tank get a 3/4" or 1" piece of plywood cut it 1/2" larger all the way around than the new tank, so it has a 1/2" lip and put it on the table under the tank. that should take any possible future problems away.

 

Like above I’m into the acrylic now. As I said earlier I had a 200 crack on me. It sprong a leak about 8” in from the bottom corner and that leak quickly became a crack that traveled from the bottom to the top. About 6”from the top it broke right off and 200 gal exited my tank in around 5 seconds.

It's scary. My lfs doesn't hold acrylic tanks I'd have to order it and that's too costly.. granted I'd love to and rather have a acrylic aquarium but like I said they don't sell those around here and for my town it's kinda a specialty item

 

Okay, so first I'll go into a cheap option to support the complete bottom of the tank, because it is completely needed.

You need to get a piece of plywood and a self leveling mat. Together, this will cost you about $30-$40.

Like had been stated. Glass is strong, however, silicone is NOT. You're twisting the tank right now, putting A LOT of pressure on those seals. Everyday you refuse to fully support the four corners, you're weakening the tank in the long run. Considering that's a new tank, it won't be busting seals anytime soon, but you are risking cracks. It can happen, and likely will if it isn't remedied soon. I would at least get the plywood and self leveling mat for now. Then use them on your stand when you get it.

 

If you can't afford a new stand for your new tank get a 3/4" or 1" piece of plywood cut it 1/2" larger all the way around than the new tank, so it has a 1/2" lip and put it on the table under the tank. that should take any possible future problems away.

Agree 100% it may set you back a little more right now but it may save that investment you just made. The stand is every bit as important as the tank and not something you can cut corners on if you can excuse the pun. Pretty it all up later get it safe for now.

 

It would be nice if the corners had some sort of reinforcement like the tops and bottoms.

 

Hello all,

How do you check the seams of your tank t make sure that all are in order?

I have a 55 gallon I got off of Craigslist and didn't ask about it's history. I'm concerned now. Can anyone walk me through how you can assess the integrity of the seams?

Thank you in advance.

 

I actually have a pretty new 75gal I purchased from Petsmart online during the past black friday...I have it set up barebottom with a FH and some plants. I have seen some disturbing bubbles in the seams and I'm hoping I won't have a horrible surprise like the one posted..Any ideas on if this is serious? Also I can't remember if these were here originally or if it was after being filled. I only noticed them after setting up with water...

 

I'm concerned now, also, tho only dealing w 20 h and 20 l. Water level seems to drop so fast. Obviously evaporation as hard water residue on tank cover, but is it all evaporation? I check all around and feel/see no signs of water....but can evaporation on a covered tank be fast?

 

It would be nice if the corners had some sort of reinforcement like the tops and bottoms.

They do. The tops and bottoms are the reinforcement for the sides. Water pressure is higher at the bottom but its still only pushing out, so the top and bottom trim pieces are the corner reinforcement. Go ahead and cut the centerpiece on the trim of a cheap 55 fill it up and you'll see how much they keep the corners in check. I'm kidding only attempt that outside with no fish on a scratched up tank you don't care about.

Yes support at the top and bottom but no support in the middle of the tank on the edges.

 

The only way you will get that is with another full band around the aquarium in the center. You could add verticle corner pieces and silicone them but they will only reinforce the seal not the integrity of the tank. Once something affects the integrity every seal will fail in time

The thickness of your glass or acrylic is not determined by how big your tank is but by how tall it is. As I mentioned water pressure presses out into the lighter air pressure. More so at the bottom because of the higher water pressure than at the top. Most tanks are built with thin plastic trim/reinforcements because the glass is already tough enough to handle that stress. The bottom trim holds the bottom up so that it doesn't have to be perfectly supported. That pane hold all of the water pressure from above with ease because it can't go any lower. The side panes have to hold less pressure at the top than the bottom but again the pressure is out into the air in all directions not focused on the seams. Depending on the length of the tank horizontal reinforcements keep the glass from flexing out to far and pulling apart those seams, usually 2 feet. Since most tanks are 2' or less from back to front no reinforcing is needed on that plane.

 

Ok I sent the new tank back and got a replacement after realizing that the new tank was faulty, the seams weren't placed correctly and the tank was not safe to me. So I sent it back and got a replacement one which looks to be built better, I also took everyone's advise and got plywood to place to new tank on therefore all four corners are flat and level


it's not fully setup how I want it right now, I'm waiting until summer when our LFS gets more aquatic plants.

 

So should we purchase new tanks after a so many years? I always worry about this happening.

View attachment 418956 it's not fully setup how I want it right now, I'm waiting until summer when our LFS gets more aquatic plants.

Looks very nice. You can also order plants from Aquarium Plants Factory. They were suggested to me on the forum and I have been pleased with them.

I'd say at least every 4 maybe 5yrs.
My theory is that water changes and the emptying and refilling of any tank will over time completely weaken the integrity of the tank and the seals making it more prone to stress fractures and detachment of the seals.
But it really does depend on how well the tank was made and what it's made from. Some tanks will last a lifetime if built properly and maintained others could collapse within 2yrs.

Best advice when buying new tank is always inspect every nook and cranny on that tank like you're Sherlock Holmes looking for his magnifying glass. Because if you don't look it over to make sure everything is in tip top shape you'll end up paying in the end

 

I think tanks are good for at least 10 years. Water changes won’t stress them that much. I think most problems happen when they are drained and moved. The moving adds to the stress. My 200 was around 20yrs old. Got it from a friend who had it for at least 10 and I had it set up for around 7.

 

Changing out a tank sounds like an almost insurmountable task....where do fish, plants , gravel all go in between??? Is a lone person even able ? Argh...didnt need any more issues to worry about. Just want my fish family healthy and well. Yes, in an intact tank.

Blaze..congrats on new tank. Good luck!

But one thing you never hear about on any fish forums, is how do people fill their Aquariums during water changes? Do some of you just dump the water quickly into the tank or do some of you pour the water into the tank slowly either with a hose or with a small jug?
Because how rapidly you pour water into an aquarium determines how much stress you're putting the aquarium through. Like if you dump a whole 5gal bucket of water quickly into the tank you're stressing the seals and integrity of the aquarium.

With that being said lots of factors come in to play when it comes to water changes and how quickly water is being added at once

I'm confused what you're question is¿

 

Ive had the same tank I had when I was 16 and I baught it used then. I'm 26 now haha no leaks

Ive picked it up full and moved it before too. I don't anymore haha

It depends on how well it was built.
If it's built right it should last a lifetime.
I personally wouldn't feel safe using an aquarium that's older than 10 years though. Especially if it's larger than 20 gallons

 

It started leaking at 2am lastnite I'm not kidding

Bro I'm telling you, you guys have to play that safe and just suck it up and get a new tank or just get rid of the whole setup completely because what just happened to you and myself Will definitely happen to anyone else who has either an old tank that they've had for yrs or something they got for free or at a garage sale.

I'm just thankful that what happened to me and you will help others who are unaware about degradation of the integrity of glass Aquariums and how a total failure of the seals will eventually happen.

Would I be able to suggest the MODS to create a thread or something about what I'm talking about on this? So folks around can be informed on Home Aquarium Life Expectancy.
I couldn't think of how to word what I was thinking lol.
