I am looking to get a tunze skimmer for xmas, and doing my research now to decide which one is best for me. I have a 65 gallon sps tank, with med fish load. The area in my sump for the skimmer has a constant water level of 13 in. but I can make a shelf if need be to raise up the skimmer, my space available is 10 x 7. Height shouldn't be an issue. So would 9005 or 9010 be best? Thanks I can't wait to get one!
