Reef nutrition

Who's using mangroves

great nutrient absorbing ability? I thought the consensus was that chaeto absolutely blows them out of the water (no pun) for absorbing nutrients.

Eitherway I think you need to spray off the leaves periodically as they get salt "sweating" out of them, also need to be really diligent about making sure leaves that fall off don't stay in your tank.
 
I used to use them on my 1st tank. They grew but I don't think absorbed near the amount of nutrients other macro algae do. I also heard they can absorb quite a bit of magnesium. If you like them for aesthetics, go for it, I doubt they'd hurt anything. The leaves do get salt on them but they still grew for me.
