Good job Ralph I mean Entice
One thing I will never do again is add macro algea to my main display, and that goes double for the grape stuff. Fuge yes, main never again.
Macro algea 's can make an impact on the nutrient level of an aquarium, but like stated it can sometimes backfire in the form of going sexual and releasing these nutrients back into the water colum almost all at once if proper care is not taken.
It is sorta like having an under water garden. some people have to prune a whole 5 gallon bucket out of thier refugiums they have so much of it.
They have there uses, tangs use them as food too.
Not really many marine plants, they are algea's.
