How often do you do a water change?

jeeptp75 · 01/19/2006, 08:07 AM

Im just wondering how often people do regular maintenace water changes. Even if things seem fine in your tank how often and how much water do you change?

lossman · 01/19/2006, 08:09 AM

We do 30 gallon changes every two weeks on our 150g.

JC2005 · 01/19/2006, 08:23 AM

I do 10-12 gollons every two weeks on my 46 gal reef tank.

Pandora · 01/19/2006, 08:48 AM

10 gal every month or every other month in the 75, now that it's established. Used to do every other week when it was newer.

Froggy · 01/19/2006, 08:57 AM

5 gallons a week on my 75.

kbmdale · 01/19/2006, 08:58 AM

about 10% of the system volume once evey other month. Seems to work fine for me, but I have a low bioload (not many fish)

lakebound · 01/19/2006, 09:05 AM

5 gallons a week on my 55. Sometimes every week and a half when I get lazy.

Billybeau1 · 01/19/2006, 09:24 AM

18 gal every two weeks in my 72.

smokinprice · 01/19/2006, 09:46 AM

Between 2 and 3 gallons every two weeks for my 10G.

miztic · 01/19/2006, 09:48 AM

10 gallons a week on my 90

Wiskey · 01/19/2006, 10:06 AM

10% weekly

Right now I do about a 25% every week or two. I'm thinking of changing to a 50 % a month so that I can have more time to do other things.

I use NSW so I have to go and collect it. If I switch to the once a month rotuine, I can collect water, do a water change and then I don't have to worry about storing water and can stack up my empty containers easier.

I've also thought about going with say a 75 to 90 % every 2 months but not sure I can carry that much water at one time. I've got a 45 G and a 500 G system.

MattG · 01/19/2006, 10:17 AM

50 gallons every two weeks.

jimdpiper · 01/19/2006, 10:19 AM

I do about 8-10 gal every week to week and a half in my 29gal.

tigerarmy40 · 01/19/2006, 10:23 AM

5g a week on my 40g reef! and once every other month I do a 50%.......witch is only realy 15g water change by the time you include rock and sand!

outta names · 01/19/2006, 10:26 AM

20-25 gallons a month in my 72

moses13 · 01/19/2006, 10:47 AM

15-20 gal once/month on a 135.

rutledgek · 01/19/2006, 10:49 AM

5 gallons a week on my 29

maddyfish · 01/19/2006, 11:23 AM

20 gallons a month on my 75. Thats messed up now since my RIO pump burned up, changed most of the water after that.

RIO pumps are fine as long as you NEVER plug them in, and NEVER put them in the water.

integlikewhoa · 01/19/2006, 11:42 AM

15-20 gallons every 3-4 weeks on my 125

wiley · 01/19/2006, 11:44 AM

5-10 gallons every week in my 35

Anemonebuff · 01/19/2006, 11:53 AM

12-18 gallons every 3 months or so.

mystikdragon7 · 01/19/2006, 11:55 AM

10% weekly, or whenever I get around to it.

Holyreefer · 01/19/2006, 12:07 PM

I try to do 25 gallons a week but i actually only do about 45 percent a month once a month

Ginzo · 01/19/2006, 12:58 PM

Can somebody explain to me exactly why we need to perform water changes ?

If water evaporates everyday and we replace that from fresh RO/DI water..isn't this like a water change ?

Also, how do you guys perform you water changes ? Is it as simple as taking a 2 gallons bucket, filling it..and dumping it in the sink and replacing that water with fresh RO/DI water ?

Thanks !
