Bacterial problems are one of the main stumbling points in larval rearing since the larval phases are long and we are adding so much food and sometimes enriched food to the tanks. There are so many variables involved that it's hard to say if the super UV water is the reason for their improvements. I don't know if it will become the norm, but I'm sure OI will continue to use it as they have had a great larval run of yellow tangs up into day 60 something. It's so cool that we are all in this hobby at a time when history is in the making! I hope OI gets their yellow tangs through to the juvenile stage this year. That would be a huge step forward.
I've updated the blog with a video of the venusta

Sorry it's been a month since I last updated. Life is crazy hectic raising larvae but it's all good!
