I've had my 125L tank up and running for about a month and a half and after adding a bristlenose plec, an angel fish and 3 clown loaches the water was crystal clear, but now the really small was bits of waste don't ever seem to clear.
I have an external filter which I done a full clean on including all tubes.
The filter is a auquamanta efx 200.
Also I don't seem to feel much pull on the inlet, it does pull but not what I would expect. Attachment 235650
You can see all the little bits in the pic attached.
