why do you think posting would go down?
True but what about just a section with titles like this
55 gallon fresh water mbuna tank
125 sw tank
25 planted cube
and people post what they do as they setup their tanks and people can help them and comment on it and that way there would be no need for sub-forums. Just my opinion

About the many subforums you would only really need:
Brakish
Freshwater
Salt
Planted
