How much water should I change out weekly?

[ironnie7i]

I have a 55 gallon tank and I want to know how much water I should take out when I do a weekly water change? Also a bi-weekly?

Thanks a lot

Most people do a 20% change weekly. In your case, 10-15 gallons.

+1 PRC.....When i do water changes i do about 20-30% water change every 2 weeks, but i also have a 120gal tank too.

If your water parameters stay good and you don't have algae problems, you could go as low as 5 gallons per week (10%).

I agree with biff...if you're consistent, then 5gal a week is perfect...or else, 10gal bi-weekly.

I do a 5 gallon every saturday(125 gallon tank)

sweet thanks guys.

That's below the norm, but..........

I only do a water change (40%) once every 8-12 weeks on my Zero Edge.
I do a 15% water change once every 3 weeks on my RSM.

I've never been normal.

 

[OhNoNemo]

Who wants to be normal anyway...lol
I look at it like,if it aint broke ,don't fix it,been doing my WC's this way for 3+ years..

I've been doing 10 gallons a week in my 55. Thinking about doing 10 every two weeks. But then again I'm having some issues so I'm trying a few new things..:mrgreen:

Really?...Do you think that it helps?

 

[OhNoNemo]

Well its not hurting anything,plus why wouldn't it,i'm still taking out old and replacing with new..I guess i never understood why there are all these ratios to everything,like WC's and CUC's and this many watts for this many gallons...Even though i know nothing about that(i have no serious corals),but i would think just because someone was a few watts off,all their corals wouldn't die.Plus, i'm just a rebel..LOL.:mrgreen:

I currently dont have an RODI system which im planning to buy. Is regular distilled water from the 5 gallon jugs from like home depot or walmart be fine?

 

[Bifferwine]

Yep that will be fine!

 

[OhNoNemo]

Well,this could get tricky,because IMO yes its fine, but guess what, I use Tap Water:shock:

No! :shock:
Mr. Rebel you take risks too!:death:

 

[kwsm]

I use Tap Water:shock:

You're fired.



:)

 

[Jmck]

Hahaha Come on, I use tap water! but melbourne water is proven to be good for tanks in Australia ;)

No RODI systems for me hehe.

 

[OhNoNemo]

IDK,whats riskier ,not QTing new fish or using tap water,hmmmm....:sfish:
Plus like i said,if it aint broke..,,never once had an algae problem,or any problem that so many people are too quick to blame on tap water...,but no,i don't have super delicate corals either..coming up on 4 yrs(August) since i set -up my first SW tank with tap...plus,all tap isn't the same, i'm sure of that...I don't think all of us could get away with it,but i also don't think one should be put in front of the firing squad for using it:mrgreen:

 

[Jmck]

Hahaha Nemo, I feel the same

Here are a few no no's i do all the time

I have no QT tank
I use Tap water
I dont really acclimate my fish, inverts and corals for more than 30 minutes.

Other than that, I dont do much wrong :P
