I have a tank of 3*1*1.5 with six chichlids. I had two internal filters earlier. I was told by some one that the water quality of external filter is much better than the internal filter. I got two external filters made. These are glass boxes 1 foot in length by 1/2 foot in breadth and height with holes in the base. water is pushed by a motor and pipe from the tank and falls on a 1.5 cm thick piece of sponge. then filtered water falls through the holes back in the tank. But the water still have suspension.
can I add some other media in the filter boxes along with the sponge? any other suggestions to improve the water filteration.
