oxygen

[justrelax]

is the spraybar of an xp2 going to agitate the surface enough, or should i add an air pump? i know surface agitation is the most important. i'm just wondering if it will be sufficient for a 55gal with the stock in my sig. tia.

yes, i point mine toward the surface and i dont use any kind of airator

it will be enough, but an air pump adds even more oxygen and surface agitation
