Here's one of my systems with a mangrove, they can be a fascinating addition or extension of the aquascaping. Keep in mind they compete with corals for magnesium carbonate so keep a closer eye on it. SPritzing them frequently with fresh water should help reduce their need to use it to filter out the salt in hte aquarium water.
