water changes

[ncfishguy]

just wondering what is your water change schedule and everyone elses ? also what is best a week two weeks or month or even do any at all

I change 10% every Friday

 

[twilliard]

When the tank runs low on salt :-)

I do 25% every 21 days. Using natural sea water

 

[glb]

10% weekly with rodi water and salt mix

it all depends on the needs of your tank.

water changes are useful to replenish nutrients as well as remove bad or excess nutrients. you can change 100% every week if you want or do 10%. the higher your bioload, the more I would change, the more coral you have the more I would change. its very dependent on the needs of your tank and how your setup works.

No water changes. o. none. NA. noghto. negative. not needed.

Love it!

I do 20% once a month.

 

[JimWelsh]

No water changes of any consequence (OK, I did a few tiny "water changes" when acclimating new livestock) for exactly a year now. Corals never looked better.

Automatic water change 2 times every day. Total of 1 1/2 gallons a day. Everything in the tank is loving it!

 

[vic5hands]

50 gallons every 2 weeks
210 gallon tank

I test my water weekly and if everything checks out then I dont do a water change. Typically my alk starts to get low first but once any parameter starts to get outside of my preferred range. The RODI gets a rockin and some salt gets a churnin

 

[Reefing Madness]

Twice a year

you also have to factor in your nutrient export and if youre dosing or not. theres a lot more to it than just how much you should change. its why you should change that much and if you should change that much.

I use an automatic system (a dual head pump on a timer) to change water about 10 times a deal for a total of about 1% daily. I spend less than 10 minutes a month to do this.

I discuss the impacts of water changes in different amounts here:

have ran a mixed reef tank for up to nine years and FW planted system for up to 9 years also with no water changes. Nitrates and phosphates unmeasureable. FW tank 10g had a more or less stable population of 30 live bearers for years.

How do you collect NSW?

If he goes this route then what happens next? What does he need to know about this method?

I do around 1% daily automatic water changes. I see only benefits and no negatives in doing them. I see no reason not to do them. I only know of 1 system that has what I would consider to be successful not doing them.
