Productive?...hmmm...maybe...
Fun...yes...
it's fun to debate, I love to do so myself...let's just keep in in perspective and have fun, ok?
In six years of reefkeeping, here are the few hard and fast rules I've figured out...and granted, while vauge, this is what I've seen in my tank...:lol:
#1 Corals need water
...and water with near NSW values seems to work best...too low or too high in a certain area and they don't seem to do as well...
#2 Corals need this water in a specific temperature range...78-82 deg. F seem to fit the bill best...
#3 Photosynthectic corals need light....the type of coral in question, placement in the tank, the amount, and type of light provided then become a matter of debate...but they need light...
#4 excess nutirents make a nasty looking tank...there are debates about the degree to which corals tolerate excess nutrients...but corals aside, if you have too much of that, than you get nasty algae and/or cyano problems...
OK...that's all the wisdom that is "absolute" I have after 6 years of reef keeping...
....lets have fun here folks, but KEEP IT NICE....or else....
