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.

Every 2 or 3 weeks. Freshwater is once 50% a month.

Depends on the tank. Some tanks per week, while on one tank almost every day (It is an automated system don't worry lol).

On my 40 oz pico I do a 50% water change once a week and change the floss twice a week. Freshwater top offs happen about 2-3 x a week but it takes like 2 seconds so not a big deal.

The 6 gallon gets a change either every week or every 2 weeks, I haven’t really decided which is better yet. Kind of leaning toward every other week. And there’s an ATO for in the meantime.

I also have a 2 gallon “tank of shame” where the menaces of reef society live, baby gorilla crabs and a decorator crab. I’ve never changed the water on that, but to be fair it’s only a month old. Only freshwater top offs so far.

I do a 3-5 gallon water change on my 26 weekly

Around once per 5-8 yrs

I try to do a 20 percent water change in my small nano once a month. I only have one small fish so the bioload is low.
