If the price is right, then go with Havey's pro clear. I have always and will always go overkill on my skimmers. It is not really the turn over rate you are looking for, it is the quality of bubbles and skimmate that it will produce. Obviously the larger skimmer you have, the larger the pump will need to be. Alot of the smaller skimmer use rio pumps and I am not a big fan of them. If you have the funds then go with a skimmer that will work with a 150 g. tank and a pump output of about 500 to 750 gallons an hour. IMO. I also like beckets instead of needle wheels but then again, that is just preference. Again if you have the boat load of money, look into german production skimmers, the best in the world. But now your getting closer to $1000.00 and up.
