mangroves and magnesium

[pasenah]

hi, ive been thinking of adding some mangroves to my refugium as i dont skim and thought it may help, and have been told they take out a lot of magnesium. can anyone confirm this?

thanks

They do use magnesium however I dont believe the uptake is very significant for an individual plant, you're going to lose more to coraline and corals. You should monitor it regardless and dose if necessary. A mangrove probably wont have a large impact on excess nutrients. A good macro like cheato would be far better. That being said mangroves are very cool and someday I'll have a bunch more.

hi david, i do have chaeto and im now thinking i shouldnt add any mangroves as i always need to buffer mag, lately anyway. i was thinking of adding 6 to a 90g.
thanks for the advise,
