    Everybody does it differently but generally about 10% every 2 weeks or 10 to 20% once a month should be fine.

    Do you have a protein skimmer, sump, DSB?

    Jakkie, please tell us more about your system, bio load etc.....
    But as Viper mentioned, 10% every two weeks along with decent skimming, running of carbon etc... should be fine.

    and Jakkie, make sure that the SG of the water you replace is the same as the tanks water, same goes with temp. Do you have anything to measure the SG with? And I assume you use RO water as a base to mix for the water change and not tap water?
