my new 120gal reef

[rayyue]

hi guys

i'm setting up my 120gal reef tank right now
i got some question
my tank size is 48x24x24
i use a mak 4 for return
and a mag 7 for uv and return
i guess the total return is around 1300gal per hour
and i want to buy a tunze 6060 for internal flow
it has 1680gph flow rate
is it too strong or not enough
most of the coral are soft and lps
some anemons and some clams

thanks
