actually, im thinking of 333, 3 side crystal glass. but the problem is, because i'm doing 3ft height, tank maker insist on 15mm. from 12mm to 15mm, crysatl glass is almost double the price. from what i hear lah. the crystal glass and normal glass doesn't cost much difference. the crazy thing is the increment of mm, not number of panels.
my lift and stairs won't be able to fit the 333 tank, so the tank has to be built in my house which will take roughly a week.
alternatively, a friend suggest doing 4x3x2.5, then the thickness maybe can 12mm and won't cost so much. anyway see howl ah still planning.
