Would the sunsun HW-603 work just as well? Maybe better?
Or would the fluval U2 be just as good?
Yeah the 603 is the same filter with same flow rate, but slightly larger so will hold more media. I like to go larger whenever possible.
I don't like internal filters in a small display tank- the real estate is too precious to be taken up with equipment.
