Skimmer recomendation
 

I will go for a 720 liter tank with a 140 liter shump. I am looking for a double cone 200 but what if i put in the tank several fish and sps coral in the future, Will be to much for that skimmer? O dont want to be on the future upset on not “upgrading “ To the 250. Thanks for the advices

The Double Cone 200 will be perfect for that system even if you had 30 fish it. Plus, SPS don't really add to the load. The 250 would really be over sized for that display and unless you had an insanely high fish load, it wouldn't be consistent unless you ran it REALLY wet. As such, I would recommend the Double Cone 200 over the Double Cone 250 for your sized display regardless of how many fish you plan on keeping.

Thanks
