What is one myth you were told about reef keeping?

We have all been told a "fact" by someone in the hobby that turned out to be completely false. What was the one fact you were told that was false? Mine was "put your protein skimmer before your refugium". That is actually completely false because if you do then your macroalgae has no nutrients to thrive off of to successfully culture. If you are going to run a skimmer it should always come after your fuge!

  • I think the old adage that there is perfect numbers for certain types of tanks. each tank is an ecosystem, and should be treated as such. What works for your buddy down the street won’t work for you.
