After thankfully testing one of my and primary livewells on sunday we realized it wasn't working- just didn't come on. I'm not sure what the issue is and really didn't look at it. Though I have a backup, I was glad we discovered the issue now vs. next Wednesday during the first Weekday Warrior Tournament.
Anyway, instead of even thinking about fixing or replacing it with the same, in my mind I was waiting for something to push me to finally install the oxygen system Rob Bertazon first posted about here and is in use now by several MRA members. I pinged one of them, Bobby Standiford who is a quite close neighbor who helped track down all the parts, review his installation and even offered to help install mine. Thanks Bobby! I hope to have this up and running for a live test at the tournament next week but that does require fish. Stress testing it with a nice limit would be ideal.
We never had issue with our cheap mayfair icechest pump/sprayer but besides the improved water quality the other benefit I wanted was one (or two if two livewells going) less drain on the trolling batteries.
For others looking to install the same oxygenator, I'll reiterate what Rob posted or linked to prior for convenience.
1. The regulator for an airtank (which you can pickup locally) is on at this link from Premier Industries. You will have to call them to order this as they don't have online ordering.
2. At the bottom of that page on the Premier site click on the link to the article Oxygenation of Livewells to Improve Survival of Tournament-Caught Bass .
3. In that article, there is a link to a Powerpoint presentation on Livewell Oxygen Injection . It steps through the setup in detail and lists all the parts and vendors for the parts. Can't make it easier than that!
