Here is option number 2 instead of the cooler. it is a cooler under my front console seat (I know it needs to be cleaned up) but it is about 10 gallons. would this be large enough to keep 7 crappie alive for 8 hours? I think this option would actually be easier also.



what do you think, first option or this one?

They took a bilge pump and added a part that makes it float in the livewell (or cooler or bucket) upside down so that it pumps air bubbles. No hoses or tubes needed. A simple design that works extremely well to keep shrimp or fish (bait or catch) alive and doesn't have anything to clog or clean out.

The oxygenator is not to replace an aerator. It is to enhance it by adding O2 to the livewell, to help maintain fish and believe me they are lively with it.

So if I don't have an aerator it won't work

Here's what we observed, read and have learned over the years of handling fish professionally in aquarium and bait tanks.

Use a livewell or aquarium circulating water pump (sometimes called an aerator pump) to circulate and mix the tank waters quickly. The low O2 waters get fully oxygenated very quickly at the surface, so it only necessary to mix the sub-surface waters with the surface waters in order to get the very max dissolved O2 throughout the water tank. (Without water mixing, the fish quickly use up the dissolved O2 and would not survive.)

The small air bubbles introduced into the incoming water stream do not add or contribute significantly to the water's total dissolved O2, but bubbles mayh be important in the incoming water stream as they can cushion the impact of the inrushing water stream force on delicate shrimp, small bait fish and such.

Injecting air bubbles, or adding even so called nano-bubbles of pure oxygen into an incoming water stream of a tank that is already having its' waters regularly re-cirulated does not put in or add any additional dissolved oxygen athough many products have marketing that indicates it.
