People with large tanks (more than 3000 gallons), how big of a water change do you guys do and how often do you do it?
Water Changes on Big Tanks

I don’t know, and I have not had and probably won’t have a tank that big. I am going to guess that a constant drip may be the best approach, but don’t know what rate may be needed. It would depend a lot on stocking (numbers and types), feeding routines, as well as water availability.
For anything but a drip system you’ll need an on demand limitless water heater. I have an 800 gallon and can swap about 150 gallons before the refill water runs cold.
