Caluerpa

[Mary & Fred]

Hello you'al   I need some advice. I am setting uo a new tank. A 45 gallon tall and plan to use a 10gallon sump. I have read that caluerpa in the sump does a good job controlling water quality. Questions:   1. How much caluerpa should I add to the sump and what species are prefered?  2. What type of lighting is need for the sump and how long should it be on?   Thanks for the help Fred
