Yesterday I bought a filter (top filter): a Sea Star HX-1480G, with F.Max at 2800L/H (which means that it has a flow rate of 2800 liters 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/turf (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 turf box, and it said "place after the mechanical-biological filtration, or hang directly in the aquarium netbag.", so I'm worried 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?
Previously I used to put flat stuff below, also the polyfiber, then the anti-phosphate and another things above it, and then all other things as it is.
Is it right?
