ok guys - i have another small tank going --- 15gal
filter is a filter box(on top of tank) which is fed by a powerhead --- and returns to tank via pipe (which i extended so it goes directly into the water) -- i know....this might hurt aeration as there are less bubbles - but the powerhead seems to be doing a fine job creating surface agitation.....
ok, so my question is simple - how much/what kind of filter media should i put in the box?
1) should i cut out a rectangle so it completely covers the entire bottom of the filter box area?
2) i bought some material (remember i am in china and have only 2-3 options here) -- and it looks like a sandwich --- 1 layer white (cottonish stuff), middle is a thick black sponge type layer, 1 layer white stuff (diff. from the cotton stuff).....
sorry to be vague....but everything is in chinese and i don't know what is going on.....
