it can run whatever amount of gallons you want up to 99 gallons, continuous (one gallon change after another), weekly (divided up over a week), or daily (divided up over a day) and you can have it in repeat mode.O wow so its a constant running water change ??? So baseckly you dont have to worry about changing water all the time just mixing salt and making sure salinity stays good where the salt water come from right ?
so for example on this build i might do 20g water change every week. so i set it to 20g on the controller and to weekly repeat and every week it will do 20 1-gallon water changes evenly distributed throughout each week.
it will automatically fill my RO water bin, auto fill my salt water bin, and automatically turn on my power head to mix. all i have to do is toss a bag of salt in my salt water bin when it warns me the salt water bin is low, will be replenished with fresh and needs salt to be mixed.
