How much water do you change weekly?

[freshwaterfishing]

Well all of my tanks i do a 20-40% water change every week.

I'm doing both at the moment and I have to say it's delicious!

hehe thats Johhny walker im drinking and that ciggarete was the California doctor approved kind... I have cleaned up my lifestyle though no drinking or smoking (I was 17 in that photo don't know why I used it) in a long time in pursuit of martial arts and it has saved me a ton of money.

Right now, I change about 20/g per day on the central setup. I will be drilling the overflow tonight or tomorrow and then kicking it up to at least 50G per day.

 

[DB junkie]

Per week.... 150-200%

I do waterchanges at least 5-6 times a week.

Since I'm brutalizing my hot water heater the waterlevel in the pond is always fluctuating, I drain then fill till the hot water heater empties, wait till right before bed and empty it again. If I have time it gets emptied again in the morning.

But when completely full I'd say I'm around 1.2K gallons.

Havn't changed any water since October on my 190g sw, nitrates are 5ppm.

 

[Wheat]

50% / week on my 55g growout

20% every other day on my 2000g system (heavily stocked and always chasing nitrate creep)

 

[chloe]

30% weekly on mym main tank and about 15% on my FHs.
then my goldfish usually about 50% then every other time the whole tank

 

[cudatim68]

Change 40% weekly on my 75 and my 55's.

 

[esse]

Weekly 50 % - 60% on the heavy stocked tank.
Weekly 25% - 30% on the reasonably stocked tanks.

 

[heavyhitter]

I change 0% every week


I do a 50% every 10-14 days.

My water that comes out of the tank looks better than the stuff going in!! Only slightly higher nitrate water comes out, my water from the tap is over 8 ph and .5-1.0 ammonia.

I have 2x 125g and a 1 75g. All get changed on the same day.
