I am a lava rock fan. Hard to beat a AC sponge.They're fine, but there are products now that give you more surface area, which means more beneficial bacteria. Breaking up some lava rock and putting it in a media bag would outperform the bio-balls, I bet.

You could add Purigen. That's great stuff.
Thanks guys I appreciate it! I will defo check it out!
I was just wondering would defo need another tray of bio media? As I have already got 2 and 4 sponges?
I don't know if more is actually better
