debating trying to put together an auto water change system
so for example
all 3 pumps will be on seperate timed outlets.
ones i have i can set for any day of the week, on and off time (obviously)
so if i set pump 1 (return pump) timer to turn pump off for 35 mins
pump 2 timer to turn on for 15 mins 5 minutes after pump 1 turns off (herbie over flow, box takes about 5 mins to fully drain once power out)
pump 3 turn on 15 mins when pump 2 turns off.
then pump one turns back on once pump 3 turns off.
those times are just random example times. ill have to actually spend a while dialing the times in perfect.
any thoughts or advice? plan is to use maxi jets (not sure size yet) and just tubeing.
now my second thought is, haveing my waste pump in my return chamber will only allow me to pump out 10-12 gallons of water before that chamber is dry. so then if i made my pre mixed tank and water tank to hold 25-30 gallons, i could set it up to do 2 water changes a week. right?
equaling approx 25 gal wc a week, 100 gal a month. plenty for my system?
hmmm
