red or black mangroves?

Any differences?

Yes, there's 3 kinds, a red, black and a white. The Red one is the one you want. if you visit the Mangrove swamp on an island such Trinidad, you'll see the red's first in the salty ocean part. As you progress deeper into the swamp, you enounter the other two, because they only tolerate the not as salty parts of the swamp. The moist finicky is the black mangrove which was not even growing in the water, but in really damp soil.

The red mangrove stays wet in both low and high tides. The black mangroves is wet during high tide and the white mangrove grows in the highest area. Both the red and black grow well in aquariums. THose are the mangroves from the Atlantic. There are many more kinds from the Pacific, I am not familiar with them.

Red mangroves are salt excluders, as long your magnesium is around 1200 then they will be able to effectively exclude salt and take in water.

Black mangroves are salt excreters, and sweat the salt out of their leaves. A 3 foot tall black mangrove will probably sweat out a teaspoon of salt every 2 weeks or so. Not enough to effect salinity, but you should brush the salt into your top off water.

Thanks, the info will help a lot! I ordered red since that is what I found most reefers I know have.
