This 3.8 gallon pico tank is a few weeks old and seems to be coming out of its ugly phase now (sorry about the blue light). I only have a powerhead at this point but want to replace this with a hang on back filter. Anyone had any positive experience with a HOB filter for this tiny tank? I would like to mainly use it for polishing the water, as nutrients are rather low.
