Hi,
I use a DOS for automatic water change and it works great. I store about 130 of new salt water in a holding tank and would like to reset my DOS total volume to 492103ml, but the max is 150,000.
If I could, that would allow me to see how much water has been dispensed and close I am to needing to refill the holding tank.
I used a float switch in the holding tank to shut off the DOS when it is low, but would also like to see the total volume as well.
Thanks
