Mangrove pod, plus mangrove "refugium"

[justinl]

i have four mangrove pods and i think tony is on the right track. I doubt the pods actually do much without larger numbers, but it has been proven that once the trees mature (like a foot long with a few branches and leaves) the effect they have on water quality is noticeable.

btw, even as an ornamental thing, it can still look great. eventually i want to have one big mangrove tree sticking out of my tank.
