A very reputable vendor on here told me to undersized my skimmer so the tank can have nutrients. I have always thought to oversize the skimmer especially with a lot of fish and sps. I ask because I'm ordering my new DT tomorrow which will be really just sps and fish. Volume with sump will be say 260-280 gallons after rock and minimum sand. I'm trying to choose my skimmer. I plan for a good amount of fish. Does the majority say to oversize it? My thought right now are for a aquamaxx Q5 rated for 300g with heavy bioload. I can save $200 doing the size below which is rated for 240g with heavy load. Love to hear how you guys skimmers are rated against your volume. Thanks for the help
