Skimmer size

[Myka]

Yes, remember that what a skimmer is rated for is the MAX. A lot of people get a 180 gallon tank, and think a skimmer that is good for 180 gallons is a perfect choice. That doesn't make any sense at all. I like to stay about 30% from the rating. So for your tank which total volume will probably be about 70 gallons (assuming the sump half full), you would do well with a skimmr rated for 100 or so gallons. I think you may be happier with an EuroReef RS-100 or a Vertex IN-100 instead of the Tunze 9005 though. I'm not a fan of the Tunze skimmers (other than the Nano does a good job on small tanks).
