I turn off my main circulation pump that drains the system and then turn on another pump to empty water from the sump directly to a drain, then another pump fills the sump from my freshly mixed SW reservoir. I could automate this with my ProfiLux controller, but I 'm standing there anyway so I don't see the point.
I do about a 60G water change about once a month. This method takes about 15 minutes to complete.
About every second month once I have shut off my main circulation pump and checked that my system does not over flow my sump. I then take a power head and blow the debris in the bottom of the sump into the water column. I then drain the sump for the water change.
Once a year I give my sump a good clean.
