Does it matter what kind of fluval i use in my carts? 204, 304, 404 and so on, isnt this just numbers on what aquariumfilter it matches? That it just tells us the shape or how much fluval is in the packet, or is the material different from each box?
Ive read that people use fluval 304/404 (or was it 305/405, whatever) If i cant get hold of this specific fluval, can i go for a smaller box like 204? (205.. cant remember the numbers)
Or is it like the blue foam, that rite size U is different from rite size K. In this case we need to use the right one, which is rite size U.
The blue foam ive tried to get hold of, but its nowhere. Nowhere in the US is shipping to Norway. But i might get hold of some fluval here...
