    hello reefers

    I was wondering I wanted to do a big water change in my four foot in the region of 100lts as I haven't done a water change for two months now was wondering if this was a good idea.

    thanks in advance

    on big water changes you need to check the temperature, salinity and PH to be as close as possible if not exact.

    10% water changes and the impact of parameters slightly out does not mater that much. Water that is 5 degrees Celsius out will only impact 0.5 Celsius.

    No need to do a water change if your parameters are good.

    I would not do such a large water change! Rather just carry on with the 10% water changes. missing a few is not that bad if your params are good. Big water changes can be a last resort if something has really gone south in the system.
