I've been reading that using AC
in a planted tank is bad because it takes nutrients out of the water. I have taken out the AC
from my emperor 400 HOB
filter and I was wondering what else I could use instead. Is filter floss a good option?
I've also noticed that there is a whitish fog in my tank. What could be causing this? I did a 20% water change, which cleared it up a bit, but it returned the next day. Could it be that my tank is not being filtered right? All my water params are ok as well.
