I would say 20 to 25 % a week is better for your tank

that's 12%, which is pretty good, but it all depends on your setup. You'll need to get a feel for it. if your nitrates get high, then do more. I've seen people do 10% a week, and some do 10% a month, so it really depends on you, but that's a good place to start.

i do 10% a week. if your levels start to rise (phosphate or nitrate) increase to 20%. it is more touch and go till you figure out what works for your tank. how have your levels been?
