It's free, which means crap quality and most definitely not going to be enough. It's like free ink cartridges that come with new printers. There is only enough to get you started. It's certainly not going to be enough.
Get this https://www.thetechden.com.au/CerMedia_MarinePure_1_litre_Spheres_Approx_20_Sp_p/900138-1-litre.htm for the top basket. One kg of Marine Pure is like using 3 kg of ordinary ceramic rings. One of the best biological filtration media. Massive surface area for bacteria to colonise on, and deep enough to promote nitrate consuming bacteria in it's middle. I use this in all my canisters and swear by them.
One coarse pad - https://www.thetechden.com.au/Polyfiber_Coarse_Filter_Pad_30x30cm_Media_Cut_to_p/aqw06.htm,
One fine pad - https://www.thetechden.com.au/Polyfiber_Fine_Filter_Pad_30x30cm_Media_Cut_to_s_p/aqw01.htm
both for the bottom basket. Don't forget to use 'SKF' in the voucher at checkout to get 10% off.
Cut to size using the foam that comes with the filter as a template.
The middle basket can be used with the Ceramic rings that come free with the filter. But there might not be enough to fill the basket. So get more.
Don't add the Carbon media. You don't need it unless you need to extract stuff out of the water like medicine.
As you can see, the bottom basket is your Mechanical filtration, that removes the large debris. So this first basket is your front line defence in removing large waste material. Your foam pads in this basket needs to be arranged from Coarse at the very bottom of the basket, then to medium and then fine on the top of the basket.
Your middle and top baskets are your Biological filtration. That's where you have media to house as much beneficial bacteria as possible. But any large waste material will clog the media and hinder proper function by the bacteria. That's why we put Mechanical filtration up front.
