    Well my wife and I have finally decided that we will be looking for a new home in about 2 years time. She also has said that once we close on the new house that I can build the aquarium of my dreams! With that being said my current setup still requires a few pieces of equipment and I'm looking to purchase them once so I want to be able to size them accordingly to handle my new system. So my question is this. I'm going to purchase a GFO Reactor that will be able to handle a 1,000 gallon system. I was curious to know can I fill it with more GFO than is needed to decrease the amount of time required before changing when the media is exhausted?

    I wouldn't, especially if you have corals, typically the first time you run GFO, you do a half dose to give your corals a chance to get used to the rapid reduction.

    Too much GFO leads to bleaching of stony corals and alkalinity issues. More is not better in this case.
