How often do you change your water?

[ScottyD36]

I have a 13.5 gallon tank that has been running for almost two years and a 40 gallon tank that has been running for just under a year. I got in the habit with my 13.5 gallon tank of changing the water every Thursday because of how the parameters could change so quickly. I also do this every week on my 40 gallon tank. I was curious to see how often everyone changes their tank water. Sometimes I think i can let my 40 gallon go a little longer but i get paranoid because I am on such a routine.

As little as possible.

I've got an auto water change, so I change a gallon a day.

 

[bar|none]

Continuous water change. 2 liters a day for Reefer 170

 

[LouisianaReef]

Weekly. It’s Sunday Funday. I hope to switch to a automatic system one day

 

[Twoddler]

My 13.5g and 220g every 2 wks

I used to do WC every 2 weeks. Now with life getting in the way...probably once a month or once every 1.5 months. Things weren't too happy but after started dosing trace elements, I have no problems with extended intervals between WCs

I do a water change on my 13.5 every week sometimes it varies on the day I do it but I get it done!

personally, haven’t done a single WC in my 40b. everything is doing relatively well. some GHA here and there but that’s because of me over feeding. now that i’ve dialed in my feeding pattern, the GHA is receding. some cyano in the sump but i feel like it’s because my chaeto is consuming my nitrate and phosphate faster than i can keep them up(so i may rip a chunk out)

What size tank do you do this on

 

[SusQ_Corals]

Reefer 425 XL. I do between 10 - 15 gallons a week.

I have a 60 gallon cube that I do weekly on Sunday 5 gallon water change and my 29 gallon 5 gallon water change as well but on Thursday’s.

Hi! I do 10% once a week every Saturday religiously. I never miss a week. LOL I am not a OCD type person, but I am when it comes to my tank.

 

[davescj]

20% every 2 weeks, 125 gal

 

[Crevalle]

Every week sometimes 2 I do 10 gallons changes in my 65.

 

[nikodemus]

Likewise: 20% every two weeks. I have a 75G plus 30G sump

 

[Julchen]

I am religiously when it comes to water changes. Every week is a must for me. Usually, I do at least 50%. I have 55gal, FOWLR setup.

I went from a 29g tank to a 125g tank and knew I didn’t want to be doing large water changes so I set up an AWC system with a DOS running it one direction to take water out and then the other direction to add water back. I would do 1 gallon a night. Then I started a refugium and was able to stop doing water changes all together. I even took my skimmer offline since the cheato was exporting so much.

I do 2.5G in my 13.5 every Friday. I also dose nightly. My parameters are always the exact same. Everyone is happy and thriving!!
