water change pole

[rosita]

I average 50% a week in each tank (5g, 10g). Sometimes it's a bit more, sometimes a bit less. I have a new 55g cycling; it will house some Malawi cichlids--I'll have to wait and see what it will need. The other 2 just seem to fluctuate.

50% every week, sometimes twice a week.

 

[graphicdesign_r]

50% weekly is 100% necessary to keep the water clean and keep the necessary minerals at good levels for my invertebrates (for molting, growth, and decontamination of harmful substances that build up).

I gravel vac concurrently the same time every week.

 

[vaderbanger]

depends on the tank
reef tanks..10% weekly
cichlid tanks 30-50% weekly
community tanks 30% monthly
pond 30% monthly

I strive for 25% weekly on the freshwater tanks and 16% monthly on the reef, but selected whenever I get around to it. sometimes I don't even feed all my fish everyday. (and I should be... I've been feeding my fish everyday for three years!)

 

[flyfly]

I try for 50s every week, but with my crazy shedule I have been known to extend it a week

Basically 50% weekly. Some tanks like the discus juvie/fry are a lot more, daily or every other, until I can get continuous established. New tanks or where I have increased the load are done as soon as nitrates hit 20 or weekly, whichever is less time.
