You will "want" one however, it makes things much simpler and all most totally automated, requiring only minor attention every week or so.

That being said, lets do some math.

Your 244 quart container is = to 230,897.2 CCs

If you ran your 2000cc air pump 24*7 you would move 2,880,000cc of air. OR you would produce 12.47 air exchanges a day. This would probably be a little excessive. OK its a lot excessive.

Perhaps 3 air exchanges a day would be a little better, so run your pump on 2hrs on / 6 hrs off for an 8 hour total cycle.

Also keep in mind that if your pumping in "dry" air, it will screw your humidity, so it may be advisable to bubble you air thru a "BONG" type bubbler before pumping it into your terrarium.

My simple bubler/air pump setup consists of:

A Jar with lid
Air pump
Bubler stone
3/8" OD Water supply line
JB weld

And looks like this:
OFF

ON

Constructin is simple, Couple holes are punched thru lid, supply and exhaust are jb-welded in place. Then connected to terrarium using 3/8" ID tubing.

Simple, cheap, and very automated. Only requiring periodic refilling of "bong" every week or so.

Complete setup:

Air flow is as follows.

Air is sucked into pump thru built in air filter, out of pump into small hose, thru the lid, out the bubbler stone, bubbles up thru water becomeing humidified, out top of jar thru the fat tube into the sealed terrarium and out the U-shaped terrarium exhaust.

If only I could visualize the air flow thru the interior of the Terrarium, but that's probably a little excessive
