Bubbles in seam of 300g Deep Dimension

[Zalick]

I've had a 300g DD for about 4 years. I new about the issues with quality etc. but it seemed to be an acceptable risk and that Marineland may have fixed some of the QC issues. Recently I've seen many posts of people who bought tanks around the same time as me and thye are now experiencing leaks. That had me concerned so I inspected my seams and noticed lots of bubbles. I should have inspected 4 years ago but I was ignorant....


Attached are two pictures. What are your thoughts? Like everyone, I have nightmares of tank leaking or exploding etc.

Are these concerning enough to replace the tank? Crystal Reef Aquatics makes custom tanks in Bellingham Washington, so I could easily get a tank from them and pick it up.

Are these bubbles concerning enough to spend thousands on a custom tank?

Crystal reef....is that the same guy who used to be in Kent/isaquah? Mike? Indoor ocean I think it was

MarineLand aquariums have a lifetime warranty. As long as you are using their stand as well. If it does leak they will replace.

Possibly. It is Mike. Mike O'brien. Do they make good tanks?

I'm not using their stand as it was too short. I have a custom stand.... And unfortunately the damage from a leak would far exceed the cost of the tank itself. The tank is in my living room on hardwood floors. :/

lol youre lucky if it leaks...slowly... but most likely if it fails it wont be slow, it will be really fast and damage your house and kill your expensive livestock if youre not home to see it happen. I would not be sleeping easy if that tank was in my house.

Id tear it down asap. That is a ticking time bomb, especially for a tank that has so many documented failures. The primary reason I went with a custom tank in spite of the price tag was that a cheaper tank + a failure > a custom tank with no failure. Obviously a custom tank doesn't mean you wont have a failure, but your odds certainly go down depending on who you use.

Thanks. Who did you use for a custom? Being in Portland, it would be easy to drive to Bellingham for a pickup.

I can't speak directly to the quality of his tanks unfortunately. My buddy asked him for a quote for his tank and mike never got back to him. Even after talking with him in person about the email request. I was there when my buddy asked him directly about him not getting back about the quote request.

Now, I have seen his tanks first hand and in person. They looked good and they held water. He has the glass cut and polished for him. All he does is put it together.

His seams that I saw were black silicone. Which I believe will hide those imperfections that your seeing. I've never seen a "œbad" seam that was black.

Thanks. He responded to my email and gave me a quote and some helpful info right away. I'm going to try and find some more info on his tanks.

I bought a used 300 gallon glass tank many, many years ago with imperfections in the silicon on one end - much like you show here.

The left side gas bubbles slowly grew larger over time and created one long air seam on the left side panel. Something told me this would not end well. It began to worry me so much, I took all the huge Central American cichlids out of the tank.

A week later, my roommate heard Niagara Falls in the basement. He went down to investigate, saw the left panel hanging on by one side, and the 3/4 inch thick glass actually bowing out like plastic or rubber.

This freaked him out so badly he just opened the basement door and went back upstairs. He said he thought the flexing glass might explode like a hand grenade. He had a good point. :worried:

All 300 gallons of water went across the concrete floor and right out the back door of the basement into the back yard. :eek2:

No way would I ever place a tank this large on anything but a concrete floor. I don't care if the tank is produced by Neptune himself, assisted by the Silicon Gods of Valhalla, I would NEVER put a 300 glass tank on a wooden or second story floor. Actually, I would never purchase a glass tank over 180 gallons - larger than 180, it's going to be acrylic. There's simply too much weight, and too much silicon and glass to go wrong.

Since then, I've learned not to accept ANY imperfections like this. None of the other seams had bubbles in them - just that one end. I did see an 150 with bubbles in the silicon once after that - and I told the dealer to get me another tank, as I sure as hell did not want that one.

Neither I would not accept a tank up to 120 gallons with black silicon. Imperfections MUST be seen in a tank that large.

That's terrible! Glad you got all the live stock out just in time...

How long did it take for the bubbles to grow? I'm not sure how quickly I can get a replacement made.... And sadly I'm stuck with wood floors.

Three months, maybe, maybe six months, not sure.

If you would consider acrylic you have the best acrylic tank manufacturer in the country in your back yard. James at Envision acrylics is awesome. He built a 600 for us and it was flawless.

After reading tons about acrylic the last few days, the comments on this thread, and lots of PMs, I'm definitely going acrylic. I already sent James an email. I'm hoping he can make me a rush tank! I'm only about 20 miles from him.

You will not be disappointed. Acrylic does have its drawbacks, if you look at it wrong it will scratch but it can be repaired easily as well.

I watched a few videos of in-water repairs and it looks pretty easy.

I was standing in front of my 55g when the whole front panel came off - WOW! It was an amazing sight that took about a week and many $$$ to clean up. I can't imagine the force of 300g exploding to the floor.
Cheers! Mark

James builds a work of art! I’ve seen two of his tanks and they’re both amazing (280g and 450g). He has years of experience and has contributed countless hours here helping our membership! Great choice:thumbsup:
