How long have you been keeping Saltwater aquariums?

[Europhyllia]

I'm interested in knowing the amount of experience we have as a group towards keeping Saltwater Aquariums.

I've been keeping reef aquariums for over ten years but to be honest I probably learned more in the last year than I have in the 5 years prior to that. Things have changed quite a bit in the last decade and I just didn't keep up with new technology/developments.
I guess my point is:
some things are learned by experiencing it and years of hands on experience matter with that
but there's also a 'continued education/study' aspect to it where time involved in the hobby is less of an indicator of knowledge.
