I wanted to know if my filter is powerful enough for the tank. Its a "Topfin 20" and the tank is a 20g. The reason why i ask is because a layer of what seems like dust has settled on the surface and i dont know how to get ride of it. I did a 25% water change yesterday and i did another today and it didn't do squat. SO im wondering if i need to purchase a better, more powerful filter.
