Part 1: Materials
Buy a good glasscutter, it will save you glass.
The good ones can be bought at a glassstore, and you'll get some decent
advice. They may also cut the glass for you when you buy it there.
If you decide to let the store do that you can skip this part, and
go to the calculation section.
Glasscutting requires a special kind of oil.
A metal lineal
This requires a special Siliconkit. It has to
be specified on the kit that it's suitable for aquarium use, otherwise
do not use it. The only ones I came accross are the transparent ones.
Part 2 - Calculation
First decide on the measuremets of the tank.
Some common measurements in stores are 100*50*50(L*W*H), 80*40*40,
60*30*30, but you may also want to create a labyrinth fishtank 100*50*35
which will be used her as an example. The glass thickness chosen for
this thank according to the above shown table would then require 0,4
First the ground plate, which would then be
L*B (example 100*50)
Then the 2 side plates B*(H-0,4) (example 50*34,6)
Then front and back (L-0,8)*(H-0,4) (example
Part 3 - Glass cutting
Determine the thickness necessary for your tank,
and buy the glass you need.
Mark the glass with the measurements(Use a CD-marker
or similar). Oil the glas over the line you plan to cut. Place the
metal linial on the glass. Best is to fix it to the glass with for
example a glueclamp.
Place the glass cutter on the glass where you
want to start the cut. Make sure you apply enough pressure. Now in
one stroke cut the glass. Repeat if neccesary.
Place the glass on the side of a table, with
the cut a little(0.5 mm)over the edge of the table. Place something
heavy on the glass on the table. Ok. Now with a firm grip on the glas
break it by bending it down with a snap, meaning you apply all the
pressure downwards at once. The glass will then break along the line.
Be carefull, it's now really sharp!You may want to use a diamond tipped
file or similar to smoothen it a bit.
Part 4 - Assembly
If necessary clean the glass with ammonia to
remove all fat(Dont use spiritus or alcohol, they are fat themselves).
Place the bottom plate on a large enough worktable. Now go and change
into those working clothes(Or do as I do, and get into trouble with
your spouse)! Open the siliconkit, and put a 2-3 mm diameter wormlike
line on the long part of the bottom plate. Do the same for one of
the short sides. Put a bit of silicon on the long part and a bit on
the edge where the first side plate will be placed. Silicon the bottom
of the side plate a little bit. Where the side plate will be against
the long front/back apply the same wormlike line.
Place the long front/back. Hold it at an angle
of 90 degrees. Place the sideplate (bottom first) on the bottom plate.
Slowly move it towards the front /back glass till it's also 90 degrees.
Use clamps to hold it in place. The other two parts are done the same
way, one after the other. Apply some extra siliconkit on all the connections
from the inside. With a wet finger strike the silicon into a nice
Let the whole setup dry for at least 12 hours.
As long as you smell the kit it isn't dry enough. After this fill
the tank with water let it stand for a day. Check for leaks.
Do a full change of the water three times during
the next three days. The tank is now ready for use.
