I updated above but in case you missed it, Rich will be discussing:
Phosphate – that word you keep using, I do not think it means what you think it means.
The drive to lower phosphate levels in reef aquaria has consumed reefers for the last decade, but is this never ending quest really necessary to have a thriving reef tank? This talk will discuss successful reef aquariums that run ‘high’ and ‘absurdly high’ phosphate and nitrate levels without experiencing disaster, possible reasons why this is happening, issues with testing, and what this might mean for reef keeping in general.
