Is it normal?

[Notsolostfish]

I have the red sea ato+ for my 200G and the ato ran 4x times today, and i was wondering if that's normal behavior for the ato to run that many times a day?

Depends on the evaporation. I have mine run 6 times a day.

Mine runs about 40 times a day, about 5 seconds every half hour. Hydros ato setup, which is a pretty fast pump for an ATO for my size tank.

was watching the tank last night and was actually surprised how often the ato (Kamoer One 2) ran...in a 15 minute period it must have cycled 8 times.

That seems normal to me. It varies on my 240-gallon. Sometimes a couple of times a day for me and sometimes five or six times. I also noticed that if I adjust my two return pumps flow it impacts the ATO too.

I would think you want it to run small ammounts more frequently, if I shut mine off for a couple hours that can be easily .2ppt.

Mine is on and off all day. Never sat and counted how many times, lol.

If your water level is constant... It's working fine.
