Hello, i deployed a couple of 3" pc fan @5v in my 20 gal horripilarium but now i can see all spikes rocking because of the the air flow.
The RO is bout 80% but i'm still afraid they may dislike it.
Should i try to direct the air flow somewhere else? Maybe it's more usefull at ground level on pots?
Also should i just leave one fan instead of two? Do they need a proper flow or it's just about dont leave the air totally still?
