3 Trays Benjamin (Filstar XL) also owns a Sunsun HW-302 filter and provided this information about its capacity;

“I found that the Sunsun 3 stage filter that I currently own held about 2 kgs when I filled two of its three trays full with the media.” (Biohome Ultimate)”

This would indicate the volume is approximately 244 cubic inches holding:

The HW-5000 is very similar to the Fluval FX6. The outer dimensions are nearly identical so we expect it will hold the same amount of media.
