    Why use DOS for AWC - Too Slow

    I understand the concept of the DOS changing out like 1g/day...but it seems like those pumps run so slow and move such little amount, it would be better to...

    Plug two ATK type pumps into APEX and use those with programming since move water faster...thoughts?

    The DOS is designed for continuous water change, so slower is better in that regard. It can do up to 30 gallons per day, so it's good for up to a 2000 gallon tank doing continuous water changes.

    You can change the interval time in fusion to make it do the water change quicker. Mine now changes 20litres a day. But I changed the interval time to between 9.30 and 16.00 hrs. As this is when I am around then it's not doing water changed while I am out. The pumps then run faster. You can set the interval time for whatever you want, as long as the D.O.S can pump that amount of water in the requested time.
