Ok heres the deal. I have a 75 gal with a sump (probable 20 gal). Moderately stocked. I am not plannng on upgrading (at least not anytime soon) but will be working on building a nice mixed reef. I have some softy's, LPS and a few Hardy SPS. Is the 160 a good skimmer for this setup. If I go to the 200 I will need to buy another sump to accomodate the footprint. I like the 160 but would rather spend the extra on the 200 and sump ?IF it will produce a difference in water quality over the 160. What do you think?
