How often do y'all do water changes?

[PaulKreider]

I do about 10% monthly..... hmmm.

 

[rebecky45]

Usually 5 gallons weekly to every week and a half. I have a 75 with mostly softies and a few lps.

70g every month or two on my 280 pending how much build up of detris is in the sump.

 

[reef life]

8% to 10% @ 4 or 5 Days on my 180.

I just started doing a 10% weekly change on my 180g. I had been doing a 10% biweekly. It has made a tremendous difference!

Do 7gals weekly, on 130g total system.

 

[ngoodermuth]

I change about 12g weekly on my 65g tank. I alternate "clean" and "dirty" changes (blasting rock, cleaning sand, sump, etc) and re-use my "clean" changes for my 30g tank bi-weekly.

Much better!

I do 5 gallon twice a week on my 100g, mainly to siphon out detritus.

 

[Torx]

5 gallons twice a week on my 120
1 cup every other day in my daughters 3 gallon pico.

 

[Reefer831]

I do a 5 gallon every 3-4 days on my 120... I like to do more smaller water changes more consistent so there are less swings… once a month I'll do a big 10 to 15 gallon water change...

15 gallons weekly on a heavy stock 100g. Maintaining low nutrient levels.

I do 32 gal once per month on my 120 gal. Using natural seawater.

Do you use a UV sterilizer on the NSW? Where do you get your water?

 

[TampaJoe]

I do 75 gallons on 300 gallons every month. So 25% a month.

I get NSW when I go out on my boat here in Miami. Sometimes I collect right over the offshore reefs, turquoise colored waters. I let it sit in the house for 1 day and use it. Sometimes I collect my water in one of our cleanest ocean going waterways, only on high tide though. The trucks that delivers NSW to LFS's collects in this same place. No UV sterilization. Never had a problem with fish or corals getting sick, in 19 yrs.

10 or 15 gallons every Sunday morning on my 180 gallon - just a habit now.
