HOB Filter for 30 Gallon Long
I have 2 30 Gallon Long, tanks that I am using for QT, when needed, hold extra plants, or extra fish. Neither tank never seems very clean. Both tanks are bare bottom.
They both have 1 AquaClear 50, which should be more than enough. I have sponge filter and bio-media that comes with it. Nothing else. Should I change the media out or add something new? I was also thinking maybe I should upgrade them to AquaClear 70 to fit more media in them?
Open to suggestions.
