As precise as I can be (after RR's post). One of these days I'll actually mark the 5gal spot on my "used-water" bucket so I can stop guessing when siphoning out water.

When I srart a 75g or 90g in Spring, I'm going to have to start mixing my own water. Then I can just use matching buckets.

20% every other week

Usually every couple of weeks at about two in the morning when all of the kids are sleeping.

I do 20% weekly with a top-off during the week depending on current situation. So far it's worked out very well. I may slip it back to every other week and check the chems to make sure they are stable.

I change about 10% every week.. If I get busy or lazy then I will change it the following week..

I do about 10% once a week also. Sometimes I get a little behind and let it go to a week and a half.
