I know that noone can give a definitive answer here, so just looking for a 'most likely' at best.
I got some phyto from a local hobbiest, but both my bottles seemed to be at a stand still for two days then turning yellow.
Was using what was left of some old f2, so thought that might be it.
I made one new bottle with brand new f2, but same thing happened.
I then learned the phyto was mix of fresh phyto added to a larger container of older phyto, before I got some.
What puzzled it me is soon after the one original bottle from my setup started turning green again:
Question is, is this most likely the living phyto or some random dust algae thriving in there?
