Water Changes

How often and how much do you change your water in your nano?

3-5gallons every 7-10 days in my 24 nano.

 

[RFD4]

3 gals every Saturday-still can't get my nitrates to 0 ppm

10-20% weekly is a good rule of thumb. This can vary of course based on bioload.

In my 15g I've been doing about a 5g WC every other week.

When I had an aftermarket 240gph pump in my Tunze 9002 it was clean as anything, but with the stock pump it's starting to get a little green but nitrates and nitrites are 0. I have about 13 lbs of LR in the tank.

We do 10% weekly on all of our tanks. The 30 g is a bit different because of the open top and evaporation we get so we are adding a gallon almost every other day of RO. You don't have as much room for error with a nano due to the small volume so weekly water changes are a very good thing.

3 gallons religiously on Saturday afternoon.. Water is made on Friday afternoon. I use seachem reef salt. I never miss a Saturday, blow off the rocks with a turkey baster every morning ( feeds the tank ) and I only feed my tank once a week. Parameters are perfect all the time. There is 24lbs of live rock in the tank.

I change mine every 2 weeks and never had a problem....my brothers tank hasnt been changed in over a year.....and all thefish are alive and happy so not sure whats going on there.

10% weekly with no problems.

In my 40 breeder ,I change 5 gallons per week with nutri seawater and then topp off about five gallons of ro during the week.

my 20g tank seems to do really well with water changes of about 15% every ten days. It is open top, so I end up adding RO/DI into the refugium to keep specific gravity constant every 2-3 days.

5 gallons every other week on a CAD 22.

 

[JohnS_323]

50 to 100g every Saturday morning. Just got done with today's ;D

 

[Scottyrock]

2.5 gallons weekly on my 24 gallon. i was doing about 5 gallons weekly but was running into problems. i think that the huge spike in mineral content too quickly from large water changes can actually be counter-productive... just my 2 1/2 cents.

 

[jettie1767]

5 gallons every other week for my CAD 22.

I've been having great success (and it is very easy) changing appx 1/3 gallon daily on my JBJ 28.

 

[Audi0s]

Interesting, do you siphon out or just use like a big gulp cup? Ha, never heard of anyone doing that, good idea though. Even if you miss a day or 2 its still only a gallon.

 

[Nickjr000]

About 40 gal every 2 weeks. Man you nano guys have it easy!

 

[dastrader]

Funny but it is a Big Gulp type cup. I just lift the return pipe (from the chiller that goes into a small HOB refuge) and fill the cup. Then put the new water in the back. I don't know if it is the best way, but it is easy and has worked well for my tank (everything growing nicely).

I have a 4 gallon pico without fish and change 1 gallon every two weeks. I top off the tank daily.
