I only have a skimmer and HOB filter, what else should I use as filter media?

[Steven777]

For Skimmer I have Aquamaxx 1.5 HOB

Power filter: Aquaclear 110 with only sponge as media

Tank is 75gal with 4 small fish (will add more)

What media should I use? Chemipure? Purigen?

You probably don't need any additional media for now with such a light bioload, once your bioload increases you can look into those other medias. When I used a HOB for my mini reef I liked using a sponge and then a couple of micron pads sandwiched between the sponges to help keep the water very clear without using any type of chemical absorption media.

You can pick up the micron pads in sheets for pretty cheap then just cut them to fit into your filter.
