Yesterday I bought a filter (top filter): a Sea Star HX-1480G, with F.Max is 2800L/H (which i means that it moves 2800 Litter of water per hour).
- 1 layer of a polyfiber pad at the bottom,
- a mix of a nitrate remover pad and a phosphate remover pad in the next layer, then on top
- filter peat/torf (any thing you call it, i got the word from text on the box, it says it decreases PH and KH) which the owner called substrate, or something like that.
In the morning i was reading the torf box, and it said "Place after the mechanical-biological filteration, or hang directly in the aquarium netbag.", so I'm woried whether I might have misused it.
I also didn't get the bacteria media.
Should I replace all these filtration layers monthly, or just the pad? I am facing higher costs due to exchange rates when importing these supplies.
(The filter has a large net so that I can't put some of my media without a pad over it, otherwise they bypass the net, and go inside the aquarium.)
Also the filter is rather full, what should I do if I want to add bacteria media?
previewsly i used to put flat stuf below, also the polyfiber, then the anti phosphate and another things above it, and then all other things as it is.
due to your answer, i reorder my filter today: The bag contains ph-kh turfs, and other things beside it as you see, you know them better, i don't know well. then the anti phosphate and anti nitrate then the polyfiber, as there were old and for the flat surface above, they didn't fit the whole area, but i think it's ok for now... and then put them together.. is it right?
