But I'm an old dude and have been owning saltwater tanks and reading/researching stuff for several decades. I'll be retiring in 2 years and plan to build a fish room and dabble with larviculture. So the topics that interest me are phyto culture, copepod culture, system automation and larviculture. Complex stuff for a simple mind, but I do my best. I look forward to learning from people with more experience than me.
