Amount of Substrate

[H]-[H]

How many layers of substrate is needed for a planted tank?
& how many kg should I buy to fill in my 65g tank?

What kind of substrate are you using? I would buy special stuff for plants.. Or just use gravel.. Or a mix gravel/sand.. About 3''..

2-3in. I have 3 in mine, the one problem i dont like about it is the fact your looking at the 2 3/4 in of gravel. Wish i had a taller tank.
