Mangrove pod, plus mangrove "refugium"

[michika]

I want to have a few of them growing on sides of my next tank. Mine aren't that big yet, probably 1ft in length, but I do notice they deplete my magnesium a bit, but when they weren't in my nano, I noticed that my water wasn't as clear, and the water I changed out was more "yellow". For me the changes are subtle, but noticable.
