The Penguin Bio Filter won't fit my tank, nor will any other kind of HOB
So here is what I have come up with...
I can use an Aqua Clear 201 Power Head (for 20 gallon tanks) with a Large Quick Filter attached. And a second Aqua Clear 201 Power Head attached to a sponge filter.
I can use an Aqua Clear 201 Power Head with the Quick Filter and also get another Fluval to replace my broken one. Only I would get the smaller Fluval2Plus so I can actually stand it upright and be able to use the air valve if I wanted. And with two filters in there, the small Fluval would probably be okay.
I kind of like the idea of getting a power head because it will circulate and aerate the water better. And then I can take my air ornaments out.
Do these filter methods make sense and will it provide all the mechanical and biological filtration that is needed? And should I go with the first set up, or the second???
Thanks again for any help!!
