which aereator for my Tracker Topper 15 live well

[Scott06z71]

I'm fishing an upcoming bass tournament out of my 2014 Tracker Topper 15 that has a factory live well in the front bench. I have to have a working aerator in my live well in my boat. I posted pictures below of the two that I'm looking at. Do you guys think the first aerator pictured will be adequate enough to keep fish alive for several hours during a tournament or should I just go ahead and spend the extra money and get aerator 2 since it sprays better and I think it might be a bigger pump? The live well is not that big. I'm in the south and it is in the 80 degree heat range with very high humidity but will soon get hotter. I would appreciate any advice. At this time I am not going to install a timer switch, I will just connect it to the battery and disconnect it to cycle it off and on for now.
