How often do you do water changes?

[Tom R]

ZEOvit users are instructed to do a 6% water change every week. My system consists of 425G + sump and I do 30G every 3 to 4 weeks.

I took the lazy way out and plumbed 3 tanks into a common sump so I could use a single ATO. Makes water changes a lot easier. I siphon crap out of the bottom of the tanks, then move my top-off pump from the ATO pail to my water change pail.

When I turn the ATO back on it refills my tanks and stops when done. I just need to remember to move the pump back into the top-up pail of fresh water when done.
