It just happened!
Toby, it happened to me.
It didn't happen to you!
I feel like I failed you.
You never could.

Practical aquarism: Black silicon x transparent, which says the logic
The probability of an event occurring is the number of times the event occurred or
possibility of it occurring, divided by the total number of possibilities in a universe
known.
That's why we say that when we flip a coin, the probability of leaving the face is 50%
and Crown 50% as there is only one possibility in the total of 2 known.
This is also why striking the 6 lottery numbers is extremely difficult
which are in the range of 1 to 53 million possible combinations of 6 numbers.
Among aquariums, we can say that millions are built every year,
shapes, different types of glass thickness under different climatic conditions,
in different parallels, by people of different abilities, and especially by using materials
many different.
Not all silicone has the same power of adhesion, some heal well but others become brittle,
some may have a not so good elasticity and break.
This would mean opening the glass as the aquarium undergoes internal pressure
and the water would leak completely.
Silicone needs this elasticity because the temperature variations make the glass
dilate and contract, if you can not keep up with this dilation the glass would open the sealing.
In this figure we can see a glass cut increased several times, we can see several
grooves or microscopic fissures.
These are the liquid silicone, will fill and adhere to form a type
of suction and strongly joining the part.
Silicon is not glue, that is, it does not change the molecular state, it does not produce
the glass, it just grabs in its cracks and when passing to the solid state this sealing
becomes resistant to pressure.
It is known that the silicone is water resistant, will not let it pass once it sticks
there will be no water between silicone and glass under any hypothesis since it is chemically
resistant to this.
- Questions to ask - With all this, how could a seaweed infiltrate
between the two and there grow up if there is not even Co2 water that is needed for your
survival?
What chemical compound will any bacteria or seaweed manufacture to dissolve this substance
being that it is not attacked by most of the known solvents except acetone
and alcohol?
What were the seal cleaning conditions?
A lot of aquariums in the world are assembled with transparent silicone,
would be of the order of thousands the reports of aquariums opening and having the reason this fungus or seaweed
growing between the glass and the sealant.
But this does not happen.
In my opinion, what happens is a sealing badly done, sometimes the hobbyist does not clean
correctly the glass, the silicone adheres to a film of fat and not to the glass
directly, causing the leak and its weakening and potential opening.
There is no possibility of a transparent silicone allowing the passage of water
and the growth of some microorganism that will corrode in the future, that is, silicone
is not an environment conducive to the reproduction of organisms.
Bacteria to adhere to their surface will require a thin layer of
biofilm that is its substrate and there to reproduce and multiply soon after,
being colonized this space by algae and fungi.
But this region has to be in contact with some water, dry the silicone is not conducive
the reproduction of life.
