Upgrading skimmer help

Looking to upgrade my skimmer on my 93 cube lps reef

What I have now is a coral life 150 hang on skimmer its hanging in my sump at the moment and fits perfect

I'm looking for a decent upgrade from this shitty skimmer but not willing to drill a hole in the sump.



Any suggestions ? Looking for a 150-200gal capacity I may be adding a 40 gal frag tank to the system

Thanks in advance
