I am running an 8 gallon AIO nano. I am attempting to run it without a skimmer with large weekly water changes. But I'm also wondering what needs to be done with an AIO tank's back compartment and filter. How often should the filter media be cleaned? There is a ton of gunk there and I've only had the tank running a couple of months.
And as another option, does anyone know of a skimmer that will fit well in a Nuvo 8? Thanks,
