If you did a 50% change, that would have brought your nitrates down to 20ppm. A 25% change the next day would have brought them down to 15ppm. 25% the next day would bring them down to 11.25ppm, then 8.43ppm, then 6.32ppm . . . on day six 4.74ppm. Of course, nitrate would be building at the same time, so it would probably take a week or more to get the nitrates below 5ppm. Only the first water change would have a huge effect on the levels, and the effect becomes less and less with each water change.

Have you recorded your daily nitrate levels? If so, can you share them?

I'm using the api saltwater mater marine test kit...i tested every second day and nitrates didn't lower a tad...maybe 20 ppm then shoot right back up in a few days...
