Are you suppose to buy something else with these? Like some type of holder??

Yes, they do have their own holders. You initially buy a pack with the holder and rim block then just buy refills after that.

Can these be used with septic tanks?

I think so, but not sure of the benefit you're trying to achieve with it. It needs a flush of water to release small doses each time. Would you be soaking it in fluid constantly?

does this come with the plastic cage to hang over the bowl or is it just a refill

It's complete ready to use. Just slot in the liquid part and fix it to the bowl.

The description says pack of 6. Is this 6 refills in total or 6 packs of 2 refills (total 12)?

Hi You get 6 complete units, not just refills
