Camp, just a suggestion. Let the manufacturer cut and test the material, if it comes back uncontaminated and they do not replace the tank, bump this thread and every thread you have started about this on every forum each morning. At that point every available option has been exhausted and there will be no question in the minds of those reading the thread.
Heck, if you do that, I will personally bump this thread each morning for you.
I TOLD THEM THEY COULD AS LONG AS I GET A TANK BACK. HECK THEY CAN CRACK A BRAND NEW ONE ANDGIVE IT BACK TO ME. I DONT WANT TO END UP WITH NOTHING. I HAVE A BUDDY WILLING TO BUY THE CRACKED TANK OFF ME TO USE AS A TURTLE TANK OR A REALLY BIG SUMP...
I GOT THIS FOR ANOTHER FORUM WHAT ARE YOU INPUTS..?
Hello Camp;
I can believe you in this instant but I think this is completely a manufacturing defect and should be brought to light. Those are indeed stress fractures but they are due to the size of the tank and the inert pressure exerted when the monomer composition is not flexible enough. Monomer composition controls the durability, water resistance and gloss potential of the latex polymer. Ethyl Acrylate, Butyl Acrylate, 2-Ethylhexylacrylate control the flexibility of the sheets of acrylic composition.
Natural monomers have a strong influence on the film's properties. Below is a table listing the typical latex monomers and their contribution to film properties.

A typical answer from companies is that they have seen thousands upon thousands of tanks and this never happens. But my advice to the manufacturer is to begin with the chemical composition of the acrylic's flexibility. Then and only then would they be able to pin point the problem. Your chemists should very well easily be able to come to a conclusion as to what polymer chemicals were used and how much was used in each batch.
And on a side note, one batch does not make up one sheet. Typical of a manufacturing company to say that also.
I think this is a bogus call on their behalf to help out a customer. I wonder how many customers this has happened to. The BBB should be forewarned.
You have one customer out of thousands, what's the problem if you guarantee it for LIFE? I think by stretching this out longer you are just tarnishing your reputation. Help the guy out already, this customer has shared this on many forums already and many people do not see his bad intentions. I think the customer just wants some closure here.
