What size air pump do I need?

I was looking into this http://www.ebay.com/itm/HYDROFARM-A...756?pt=LH_DefaultDomain_0&hash=item56479828fc
Would that be sufficient or do I need something else? I'd really just like to use one pump (two if necessary) to provide O2 to all of my tubs.

For that sized tub i just used a single one of these http://www.mrpets.co.uk/index.php?moreinfo=10316&gclid=CIrxs_Sk57ECFQFItAodDn0ARA coupled with an old crusty £1 airstone. Worked just dandy

I'd say go for at least the 110lpm commercial pump. Thats what I use for 8 waterfarms or 5gal buckets and I would still like more airflow. Just make sure you put it outside the grow area and put a fan on it, they get HOT!

Air pumps need to run 24/7, If you can find the most energy efficient pump your already saving money.
I buy the General Hydroponics- Duel Diaphragm 20lpm air pumps from Horticulturesource.com

This pump produces 20lpm @ 8 watts per hour, The pump does not get hot.. is very quiet.. has 4 outlets and a rubber vibration dampner. They are more money up front but pay for themselves over time by using less energy to run and cool.
I would recommend one pump per grow site.
P.s. I use 2 pumps per 20 gallon grow site in my flower room.
