1/20 hp blower fresh air system?

OK, so I've never entirely grown hydro I had a little system I built a few months ago that seemed to work very well but I was having algae problems and being such a newb to hydro quickly ditched the system tore it apart and put the plants back in soil (vegged in hydro system for probably 2 weeks) anyways, I have some vermicompost going which I plan on switching to permanently but in the meantime I decided to build a hydro system and do a run for fun to get me by untill soils done. Now please help guide me in this, I have a brand new 1/20 hp dayton blower Ive had sitting around for a couple years now could I theoretically attatch that to my system and run air lines around the resevoir/roots for constant fresh oxygen and run my pump constantly? Or am I completely thinking of this wrong. I am no hydro expert, but I love making things which is half the reason I'm doing this hydro run so I can build something useful with spare parts laying around.

you talking about blowing fresh air near the roots?

if so, you need O2 in the water not the air around it.

So I could use the blower to push air through the water correct?
