Im a newly active member here who just started a 40B planted tank 2 weeks ago.
I have a 58G mixed reef that I've had since 2004.
Right now, I feel like some of you might feel about saltwater about freshwater - new, nervous, uninformed, making mistakes
Its really all about experience. Although, with my SW I started VERY slowly, gradually getting more complex - whereas I just started a high-tech planted tank right from nothing. I will say knowing saltwater helps with things like water chemistry, ph controllers, and having alot of the equipment already.
