In my bigger tanks I use both the small corner filter in some and in others I use any other ‘old’ pump as long as they are not too powerful. (eheim powerball, smaller fluval pumps) I ‘wrap’ them in the hmf filter material (as in Dorothees photo) – and I use the tyoe with the bigger holes.
Even though you dont need strong current in paro tanks, and small bubble filters are good in smaller tanks, – but if you get around 50 or 60 liter, I think it does make the waterconditions more stable with a bigger pump and more filtermaterial. I seldom change them or rinse them, thats the advantage of having a big hmf piece in the tank.
But it is nessesary to ‘slow’ the flow down, – this I do by wrapping the hmf foam around the pump, covering the output thing, so that it only gives a tiny bit of circulation. (it doesnt look pretty, and is often quite clumsy, but after a while some leaves or moss or a piece of wood will hide it)
