SPS Veterans, how often do you do water changes?

[Fliger]

From all the SPS veterans, I'm just wondering -

How frequently do you perform water changes?
What percentage of the total system do you change?

I used to change about 15% monthly, but on my new system my goal will be 15-20% twice a month. Even with a good skimmer and other equipment, it seems like my SPS always appreciate the addition of clean water, I wonder if its more the trace elements of a good salt - more than the dilution of the pollution.

Thanks,

David

Read my sig I perform a 30g water change once a month (20%). This is on a 150g tank. My orp ranges from 380-410 without any additions of ozone or carbon. Fliger, where are those pics!!!!!!!!

i do a 5g waterchange before every topoff (twice a week) in 150g of total water volume.

thats like 7.5% a week, so 30% a month.

 

[nemofish2217]

10% weekly here

20% every week or so - I have a big mixing vat (300 gal) and it is easier to do more rather than less - end up buying salt 20 buckets at a time (but it lasts almost one year)

What do you mean by veteran?

5% each time, twice a week for me.

 

[rutz81]

10% every 7-10 days

 

[MiddletonMark]

I do between 15-20% every other week, on average.

i dont know if i am a veteran or not...

i used to do about 25% every 2wks.... i have dropped back to 25% every 4-5wks... little happier now.

20 gallons every week on my 65! its a bit much but makes a world of difference

 

[golfish]

20-25 gals when I do em. I really have no set time to do water changes if the tank is doing good. I try to do one every month or two.
