How much water do you change weekly?

[tcarswell]

I have to change 50% of my water usually every 4 days to keep nitrates down (My water has unusually high nitrates from the tap) But I was curious how much you guys change weekly. Please list tank size

Thanks all ,

40 - 50% weekly so far it is a 20 gallon tank.
Just got a 33 gallon (36X12X18) that I will set up soon enough, need to make a stand for it first.

300 gallon tank + 200 gallon sump = 500 gallons total.

I change 125 gallons (25%) every weekend.

My nitrates so far never go above 15ppm in the tank. I have zero nitrates from the tap which is strange considering I live right in the middle of farm country.

Nice , you got the sump hooked up and im assuming all the other cool stuff set up ? Very sweet congrats.

PS Do you have any tiger barbs left ? With the Oscars and all....

50% weekly.

My nitrates never get over 15ppm which is pretty good considering my tapwater tests at nearly 10ppm ammonia out of the tap. I could probably get away with smaller changes, or doing it every 10 days, but I figure as my fish grow I'd need to step it up anyway.

Waiting on a third impeller to try with the closed loop.

PS. Every time I read one of your threads I want a beer and a smoke.

About 20% twice a week from each of my 120Gal's 4x2x2Foot tanks .
