How long do you go in-between water changes?

I try to keep it at every 2 weeks but sometimes it will go to 3 depending on how buy my schedule is. The longest I let it go is a month but I do pretty large water changes (around 50%) each time so I do not fret too much about it.

I change water three times per day by AWC.

Rarely only when Imy salinity needs to be bumped back up to where I like it.

13 gallons in the 180 every week. I try to make it "Water Change Wednesday" but usually it shifts by a day or so depending on my personal appointments. But every week or so. I don't like to let it go more than 10 days.

In my DT its weekly. Frag tank is monthly. Freshwater tanks are usually every few months or so.
