How Often Do You PWC?

[Tentacles]

I do a weekly change of about 5 or 6 gallons out of my 55, so 10% weekly, and its the cleanest tank Ive ever kept. 2 crayfish 4 bala sharks a gourami and a catfish.

 

[collegelife101]

10-20% weekly. It adds up with 4 10gal and 2 20gal tanks.

 

[Musket]

I do approx 40-50% once a week unless more is needed (son dumps the whole can of fish food in to feed his fishies..or I didn't take the fruits or veggies out soon enough or sick fish or something like that).
I do more for my betta tanks because they are small and I feed twice daily. They get every other to every 3 day 100% water changes, except the ones with eco substrate, they get about 90% water change at the same intervals as above.

1/3rd weekly

 

[Asher]

35% every 3weeks to a month now that the tank is established. I used pimafix everyday for a week once and it took almost a weeks worth of 30% PWC everyday to get the water to not be cloudy anymore!

 

[Elmware2000]

I don't see an option for 1 1/2 weeks but that's usually how often I do my water changes. Usually on Sunday or Wednesday. I usually change about 25%.

 

[fish_4_all]

50%+ once a week, tanks are 70% plants with tons of fast growers.

 

[physicsdude]

I do a 33% percent change every week. That means I siphon the undergarvel filter thoroughly, which removes roughly that much water each time. It has been that way for 2 years now and seems to work fine.

On the 29G I do 35 - 50% weekly
On the 10G I was doing 50% weekly when the bettas were in it; now that I have dwarf puffers I'll be doing changes more frequently until I'm confident that the tank really IS cycled. Then they'll go on the 50% weekly schedule unless I see that more frequent changes are needed (will be testing ALOT over the next few weeks)
The 2.5 and 3 gallon betta tanks get twice weekly 30% water changes
The 2.5 with the two female platies gets a 50% water change every day (those girls are poop machines !!)
