Start Simple?

Basic water chemistry discussion? What is in sea water, what we are trying to add and why. What salinity, calcium levels, ph, alkalinity, trace elements... effects of evaporation, too efficient skimming, heavy fish/coral loads. The make up of RO water.

Or topic like basic equipment and how it operates, proper maintenance, choosing equipment to suit individual needs. Filtration, lighting & gizmos.

Or topic like proper coral mixing choosing tank mates sessile or otherwise...

I like to talk about all of it, what does everyone else want to discuss in depth?
