Water changes - how large and how often?

[sid700]

I'm just wondering how others do it. I'm changing about 12% of total system volume per week.

 

[Coral reefer]

Depends on bioload and feeding etc... I go with between 10-25% per week

 

[hiepatitis]

I have medium bioload, heavy skimming and prefer to change it every 2-3 weeks at 20% because I'm lazy.

 

[northbay-reefer]

10% every two weeks seems to work fine for me.

 

[sfboarders]

I do 15% every week.

 

[Gonzo]

Yea, I go with 10% every two weeks and check my nitrates along the way.

 

[anathema]

I change 20-25% every two weeks but sometimes I get lazy and skip.

 

[tuberider]

I try and change half the water volume per month spread out with once a week or ten day intervals.

 

[Kensington Reefer]

I change 30% every 10days on home systems and 7-10 days on service accounts. I also feed alot. The solution to pollution is dilution

Can't argue with that. I've seen what it does for your mystery wrasse

I change 20 gals per week. System is about 145 gal.

Erin pretty much uses firehoses to get her done.

I admit to being terrible at this - I would change about 10-20% once a month, to once every 6 weeks.

 

[Tumbleweed]

30gals a week on a 120gal system.

how long is the "garbage can" life of salt once mixed????

 

[rygh]

I change about 5% once a month.

 

[mavjoy]

15 gallons on a 57 gallon system..will be doing 5 gallons on my 20 gallon.

If it is in a sealed container and constantly mixed you are good for a coupld of months. The key is a seal container to keep in evaporation and to constantly keep it moving.

10% every two weeks seems to work fine for me.

I forgot to add that I also do a large water change 25% once every 6 months, this is when I clean out equipments/sump,fuge/anything dirty ... It is very important to match the make up water parameter to the tank before doing a large water change. Come to think of it, I have to do that this weekend ... yike !!!!

20% once a month- low bioload & lmed/low skimming.
