Tank Confusion

[carsona246]

20% once a week is once the tank has been cycled. I've never kept ACF's, so I honestly don't know how much waste they put out. I personally don't think turkey basters are gonna cut it for a twenty gallon tank. The only real way to know how often you will need to do a waterchange is to test your tank for ammonia/nitrite every day to see how much builds up. I'd aim for less than 1 ppm of ammonia and less than 3 ppm's of nitrite.

I do have a large siphon for cleaning and water changes. I just use the turkey baster for the little stuff in the smaller tank (currently)
Thanks for the numbers!
