should i switch skimmers ?

[E-A-G-L-E-S]

i have been running a prizm skimmer for 2 weeks.
i am thinking of switching to a cpr bak-pak.
it would be my prizm w/ brand new surface skimmer attachment and $85 for a new cpr.

should i do it, is it worth it ??

sorry this is for my 37g. not the 90g.
it is shrooms, zoa's, and LPS.

Thank You

I think it would worth it, but I would look for something used.
