Water Change Frequency

[Mike]

How often do you perform partial water changes?

I try to do 10 gallons a week on my reef tank.

 

[kallililly1973]

I have 7 freshwater tanks ( thanks to Fishlore MTS-itus )and do my best to give them a 50-75% WC every 5-7 days.

I try to change mine weekly, but frequently end up forgetting and having to do larger water changes less often.

 

[NC122606]

Uhhh, I have to admit I do every 2 weeks.

 

[BlackSkirtTetra]

I’m not good at remembering to do water changes so mine alternate at a frequency between once a week and once every three weeks.

 

[CMB]

I’m not good at remembering to do water charges so mine alternate at a frequency between once a week and once every three weeks.

I honestly don't want to admit how similar this is to what I do.

 

[FinalFins]

I do mine weekly even if nothing is wrong. I do them religiously.

 

[StarGirl]

Once a week 25% most times. Once a month I do 50%

 

[BlackSkirtTetra]

I feel like daily water changes is too much for those with MTS. I can imagine changing the water of a twenty or thirty gallon tank daily but not several tanks that size. Where would one find the time for that?

 

[RyanC14]

Usually, 50% weekly, 25% if I'm feeling lazy

 

[GumYu]

75% weekly, no illnesses in 1.5 yrs

 

[CaptainGratin]

30-50% every 5-7 days

 

[MoshJosh]

I’m doing daily on my discus and fry tanks. Weekly on my 75 gallon community and every 1-2 weeks on my planted nano tank (try do it weekly but sometimes it gets put on the back burner).

 

[jinjerJOSH22]

I do anywhere from 20-50% every 6-10 days depending on the tank. Mike it'll be interesting to see how often people clean their fliters. I know I should probably clean mine more often

 

[TheFishmonger]

I used to do 25% daily, then 50% weekly.. Sometimes I left it for two weeks. Now I am doing 80%-90% weekly for clear water.

 

[toeknee]

50% weekly. Filters get cleaned once every two months.

 

[mattgirl]

While cycling at least every other day. Once cycled I do no less than 50% water changes on all of my tanks each week plus one week each month a do a bigger one to reset things. I do a 75% water changes every other day in the tank holding my pleco fry.

Yeah I have a list going of polls I want to make and plan on doing them frequently. If anyone has some good ideas on polls feel free to pm me!

 

[Elkwatcher]

50% weekly except the shrimp tank... 10% Rinse filters in tank water alternately every few weeks, I'm amazed how dirty they get.

 

[Feohw]

I do at least 50% once a week. Usually around 60%. Less on shrimp tanks. Sometimes if I'm bored I'll do a second a week. The last two weeks I've only done 30% changes as college has me wrecked.

Well I mean that's the responsibility of having many tanks. This hobby requires lots of work. (not that much actually)

 

[PascalKrypt]

Percentage and frequency really depends on the tank.. though all of the stocked ones are on a 25% weekly minimum (though I'll admit to delaying by maybe a week on the largest tanks once every two months or so, followed by a much larger change in the direction of 50-70%).
The smaller ones I keep up always, also some of them are on daily or bi-daily schedules. It just depends on the tank though. If it is understocked I might be tempted to delay a change, but I would never delay on an overstocked or grow-out tank.
Hence to me it is a know-your-tanks game.

I once had a case of OTS that wiped out a stock of fish that I'd grown attached to, so I definitely would not delay a change more than two weeks... and also not less than weekly for a good month after it got delayed by that much.

 

[Morpheus1967]

I have a 20 gallon and a 125g and I change 40% on these tanks twice a week. Wednesday nights and Sunday mornings. So guess what I am doing tonight?

Also wanted to say on the 125 I have 2 canister filters that I break down and clean monthly. So I will do the one on the left on a Sunday morning, then the one on the right two weeks later, then the one on the left 2 weeks after that. That way I am cleaning the filters once a month with as minimal disruption to the ecosystem as possible.

Weekly, I have a lightly stocked and heavily planted tank so I probably only need to do it every 2 weeks, but every week is more fun. Who else here thinks cleaning the tank day is the best day of the week? My family thinks I’m crazy for thinking this.

I agree with you not your family lol. It doesn't feel right if I don't do something.
