Eheim filters

Hello,I have a 72 gallon marine tank with 2 damsels and getting an
Emperor Angel in a couple of weeks and was wondering,i have a fluval
304 on my tank with a prizm pro protein skimmer amd 40 pounds of live
rock and my problem is my high nitrates (40 ppm).I cant seem to figure
out the problem.I was thinking on upgrading my fluval to and Eheim 2217
filter that goes up to 159 gallons.So im going to run both but with the
new filter do you think it will bring my nitrates down?Thank you.
