I recently bough this Soil, as required dirt for aquarium (i don't know how to say in your language that desn't mix with specific kind of dirt, but the thing that root of plant live within). Here are some images:
The seller said it's good foryour plants , and it contains muck(or equivalent), and it help my plants. I have 90WX30dX40h tank, which is filled with semi small and big grit, with height of around 2 or 3 centimeter. small filter inside tank that contains nothing special, soon will add a hanging on small filter, which may fill some part of it with bacterial things(which i don't now about), and remove one sheet of active coil due to that.
Ok back to aquarium soil... first... is this alone enough for aquarium? i didn't find any tutorial, or one that i find and randomly it was also in stackexchange, it used too many special word, which is unknown for me, made it very hard, second, i have very low budget and aquarium stuff are very expensive toward my earning. Ok so the question are: 1. It says for typical 60CM tank (57L) recommanded usage is 8~11, so my tank recommendation should be around 15~20, but the package says it's one litre (first i filled most of the tank with grit and i have low budget), so does this enough for not too many plant (i mean buy providing requirment, not keeping the root of plants)? 2.can it fill the cover the floor(90X30) how many more do i need to reach the need(due low budget), not recommendation? 3.do i need to use any thing else beside it (hope fully non expensive stuff)? 4.does it hurt for fish or snail? 5.where should it be? below or top of grit? 6.it says it help bacteries, but does it provide a place for them to live or i still need other things for that(and again below or on top?) 7.i have two big and a very small air stone, which i put them at the very buttom, and i like to hide them, does they hurt these soil? the package seem to be wet inside and have steam on it.
Here is some photo from my aquarium to specify the grit i used, or filter, or cooling, ...:
