Who often do you do water changes

[tendar]

Here is a new poll that may help those starting out on how often to do thier water changes.
So the question is

[tendar]

I do one every month but some times more like this month I did several since I was having a algea out break do to a couple things all happening at once and now the algea is almost gone with the extra water changes and fixing a few thing and running some carbon.

For me it depends on how the tank is doing....I have done it as fequently as every other week and have gone as long as 4 months....

[MichaelD]

what about % of water that you change?

I change about once time a month. If the tank looks good I change only about 10% if not so good up to 25%.

[tendar]

I do a 20 gall water change on my 90 once a month.

[travid]

In our breedding tanks, every day the tanks are bottomed syphened and topped up with new water, so we do approx a 4-5% change daily.

[Amphibious]

100 gallon system including the sump. Change 5 gallons every two weeks.

[Salty Dog]

20% once a month.

[brody98]

25 gallons on a 75g w/20g sump every 2 weeks

[tendar]

Well I have gone to 10% evert 2 weeks on my tanks.

I sure I would do more water changes is I had a ro unit at home. It won't be long tell I have one.

i have a 5x2x2 foot tank with plenum filter in sump, the setup has only been running since september 2003 it is a reef setup in which i do a 15 gallon water change every 2 weeks more when outbreak of algae, i have just got over a severe outbreak of brown algae by syphoning it off using small airline tube which usually removes 1 to 2 gallons which was then topped back up using already prepared water

[HI SALINATY]

I change 10 gal at least once a month in my 55 gal i would do it more often if i did not have to drive 30 miles to get ro-di

[Glow Bug]

I have a 60 Gallon tank. I change 1/2 gallon per day.

[karl]

5 gal every 2 weeks (37 cube + 10gal sump)

[NeilsReef]

25% to 30% once a month.

[Tom]

2.5 gal every couple of months

[Flame_Angel]

I do 2 gal. on my 12 gallon micro reef once a week and 10-20 gal. one a month on my 110 gal.

[Tom]

I change only 5gals every couple of months...my water always test 0 for nitrates, phosphates...must be that huge bed of algae in my sump...I do remove a couple of handfuls of it every few weeks for nutrient export...I wouldn't change water at all if I didn't siphon off detritus and the occasional bubble algae.

[Doug72]

I have a Juwel Vision tank and do a change approx 10-20% every 6-8 weeks.

[ReefGuy]

I have a 125 gallon Reef that has been going for over a year with only 1 water change, and that was due to flat worms.

[seawillow1]

I usually do a 15% about every two weeks, unless there is a condition that warrants that I do one more often...like hair algae...yuck!!!!

[mbeach66]

every 3 weeks 25% to my 40 gal

[Coral104]

I have a newly set up tank of 3 months. I have done one water change so far but plan on doing it every 2 weeks from now on.

[tileman]

I change out 15 gal every week, but I have a lot of fish in my tank
