Red mangrove tree died?

[possys]

I got 5 red mangroe trees 2 in display tank and 3 in sump. First tree died about 7 month ago in display tank and 2nd died a few month later. Now, one in my sump died too. Everything looks good in my tank. I know the rules about 1 tree per 15G water. So was this is tree died natural or ???

By the way I did dosing Mag and other two was very healthy

Your link isn't working.

Can you post any parameters? Were you testing for Mg or just dosing?

Well you definitely shouldn't be dosing Mg if you're not testing for it.

What kind of lighting were you providing for the tree in the sump?
