I have a 90 gallon tank that has no sump. I am moving (hopefully sooner than later) into a house. Im hoping by like spring. So what I am doing now is buying everything I need, piece by piece, to add a sump to my tank. I am torn on what I should buy. I already got a new 40 breeder for the sump. I need a skimmer, and the best submersible pump i can find. I was thinking of going with the new Reef Octopus Diablo 225, which is rated for up to 200 gallons, and a EHEIM 900 submersible pump. Which i think can be used as an internal or external (i think). Any thoughts??? I want the most reliable and quiet choices I can find. My only issue with the skimmer is that it seems a little huge. I know u guys can help me out on this one.Any other suggestions would be appreciated. Thanks
