Bio balls vs. filter socks

[Grelby]

I was thinking of switching to filter socks. What is your take on it. Which is better?

I stopped using filter socks and it seems like I have more PE on corals, as well as brighter coloration. Both are anecdotal.

I vote neither.

I use both...lol. But for me they serve two different purpose. I run a probiotics based system. Filter socks help me to get rid of the crude and larger food particles and ceramic bioballs with siporax house my probiotics which keep nutrients down.

2nd the neither. I use a sock on water change day only. Bio balls? that's so 80's
