Livewell issues

[hpdi200]

I have never had a problem keeping my fish alive in the summer months until I purchased a new Skeeter 2 yrs ago. Just during the summer is when I have trouble. I know how to add the ice bottles, and additives to cool the water and all. I have been doing it for yrs. I have the oxygenator in my live wells. Suppose to be a great thing, but I am not convinced of it. This is the first time I have had it in a live well. I have talked with the owners of the company, did everything they said, and still have some fish die, or just not act right. I have tried everything. Not all die, but have lost several in the past 2 yrs. smaller fish as well as big ones. Has anyone else had issues such as this. I really love everything about my Skeeter, except this.
