sorry to re-post but need some help here.....
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.....
reason i ask: before i got the 3-layered sponge material - i had basic filter cloth - and when i layed 1 skinny layer down covering the entire bottom of the filter box - the water would not drain quick enough once the exhaust hole area become slightly clogged.....so i am wondering with a sponge (because it has layers) if although i cover the entire bottom, clogging will not occur because of the multiple layers, etc....????
