Now when you know the shape and dimensions, it is time to choose the glass. It is generally sold according to the strength or safety factor. 3.8 is the most common and it is enough, but it isnt the best. You should choose stronger glass if the tank is larger and it must withstand more pressure. The iron glass is truly an alternative to consider. The main reason is the transparency it offers. It is much clearer than ordinary glass, making the entire tank look much better. On the other side, it is more sensitive to the scratches, so make sure you use it with care. The glass is always linked together with a silicone. Make sure you apply only an amount of it which can be used between 3 and 5 minutes, or it will develop a crust and connecting the glass panels wont be very effective.
Open or closed tank
The next step is to determine which type of a tank you really want. Is it closed or open type? Open tanks mean that they dont have a lid at the top. They are more beautiful and simpler to make/use. However, a jumping fish cannot be kept in them and falling items are common to find inside. Closed ones are safer, but dont look as good as the first type. Your choice.
Overall
Following these simple tips will help you get a custom-made tank of your dreams. Maybe they are simple, but these are key elements to consider.
