How often do you change your water?

[Reefiness]

Lol im on mobile and i dont see the poll.

Sorry, didn't actually notice this until I tried checking on the results of the poll late last night before I went to sleep which was on the mobile app.

I used to do bi-weekly water changes for 6 years but now with my upgrade to a 250g I do every 30 days if 15%. Been doing this for 14 months now & going great! Saving on water & salt! [emoji41]

I do 10gals on my 29gal biocube every two weeks or so with RS coral pro. I used to do 5 every 2 weeks till my skimmer went out.

I've been doing 10-15 gallon change daily as I've been fighting an algae outbreak. I have a 150 gallon system. I can't believe how much better my coral looks. I'm going to keep it up for another month. I use RSCP

1% every day at 7:00am
Once every couple of months I make up a new batch of IO

I have a little over 500 gallons in my system with an overall stock list smaller than people with tanks a fraction of the size... So my vote was Monthly 11-20%.. never mind the fact I moved away from acropora and heavy on softies and some LPS now.

Each system is different, however.

I was watching a seminar on YouTube from a chemist from another country who has a reef tank and hasn't done a water change in years he says if you get rid of all the garbage in your aquarium and add what you need back in he doesn't think you need to do water changes. I haven't done a water change in over a month but I use a skimmer have a sulfur denitrator and dose element's back in. So far corals and fish are doing awesome in my tank

I restarted my sulfer reactor. It does wonders. Biopellets are worthless compared.

I do mine once a month. I feel if everything is thriving and growing, no need to change the water often. I just do it once a month to replesh some nutrients that I don't dose with

Amen!!!

Water change schedule varies really on how you export nutrients so if you don't really have a issue with nutrients weekly water changes are a waste of time unless you use it in place of dosing. In the past I had more issues doing lots of water changes vs doing them as needed for what ever reason but after 20 years I know when it's time for one

I usually change 10% weekly like most hobbyists. recently an unusual set of circumstances arose in my life and I needed two weeks in a row of water changes-- guess what-- my tanks ( 3) look much better!! Sand is spotless and back wall is clean and clear! The only explanation I can come up with is my source water is suspect-- even though I use a booster pump/double linked RO/DI system! its not the salt as I use both a basic salt mix and a reef mix in the various tanks. I feed them differently ( all fish vs mixed invert/fish/coral aquariums). Its a mystery. But it does have me thinking the weekly effort makes me feel good and more responsible, but it might be zilch to my residents?

I am not sure how much water I have . It's a 57 g tank and a 15 g sump after sand rock skimmer fuge rock in sump ??? Well I change 15 gallons every other week with instant ocean. Use low dose of kalk in my ato . Mixed reef mostly softies few Lps and few sps .

 

[themcnertney]

I do weekly 30 gallon changes on my 220.

I call it Water Change Wednesday #wcw

 

[HoaglandDiver]

Automated 6.2 gals per day on my 150 gal system

NeVeR!

I like the idea of all the questionnaires I've seen on here lately. Compiling data seems like something that would be useful in this hobby. We all pass along things like changing 20% of your water every week or two, but it's interesting to see that more than half of the respondents do, in fact, stick to that.

I've been doing monthly water changes of about 10% with Aquaforest salt as long as I've had my tank (a couple of months...)

I've been thinking about the process and seeing people with well established tanks who feel they no longer need to do it, and of course the Triton method stuff.

I do think that it makes intuitive sense that new water needs to be added to the system. But that comes in through top ups I suppose. So it is just the salt and other elements we are adding, and that can be managed other ways.

In terms of extraction we see that chaetomorpha is clearly a very good way of managing it. But that doesn't remove other impurities necessarily.

It seems to me that some kind of water change is probably a good thing. But maybe a minimal / continuous set up is better? Or maybe once or twice a year?

Or maybe it's 10-20% a week and most of us have it right... Though I worry about stripping out too much of the good stuff with that.

135 gallon so i only do around 30% once a month ,i don't like to do them becouse my idea is if you use a skimmer that you see that is doing its job ,a refugium whit lots off cheato, and dose essential elements once a week i don't think i need to ,but whit that i did one after 3-4 months whit not doing one and my rodi water was full of phosphate so whit in a couple of weeks i had a real bad algea problem so so far i have been doing them but once it clear up completely i don't think i'm going to any more going back to my original idea

 

[Randygus01]

Personal tank I do once a week water changes and dose calcium. I also replace filter floss once a week. I clean my skimmer once a month. Also I have an ozone generator and carbon reactor. (overkill maybe but my water is clear).

My mothers tank gets 2 water changes a week at 5-10% but it's only 20 gal. No protein skimmer (yet) it's way overstocked on live rock and has a 3" live sand bed with no sump I keep microalgae in back of aquarium which the fish must eat because we always have to add more. Filter is cleaned once a week and changed monthly. Also has a biowheel which I think isn't nessesary but came with the tank. + my mother has a habit of over stocking her tank thanks to a bad Lfs who convinced her to buy a long tenical anemone. I am actually surprised this tank has not had any major problems. Probably because she does 2 water changes a week. I image when I get the skimmer in it will be even better. Pict is if her tank.

Why no pole for daily? I do 2 gal daily 14gal a week
