you can always use an air stone like the rest of us.
Funny, figured you as a veteran, would consider that a given...
then why the pump? It does add heat if run much especially in a tiny res, while it does not add any o2.
What is a fine temp?
You must have never grown with floranova, everyone knows how it leaves a film in the bottom of the reservoir, this helps. I have a rather large air stone, and the temp stays around 75...
Ok, though 75 is too high.
I use dynagro.
use bloom nutes or supernatural
