I had a brief period where my nitrates were high... First reading was 160!
I did back to back 50-75% PWC/day...
After about a week or so they were under control at a normal level... Wasn't a fun week, but I kept picturing every bucket of water making my fish healthier and it made it okay..
So, generally did 2 a day... If you can't do back to back.. One morning, one night...

You can do 2 a day. You need them <10.

2 a day is the best. DO NOT do 2 right after the other, too stressful. Good luck!

My levels were crazy high at 160 and I had to do 2 back to back PWC's to even begin to see lowering of levels... It took a week of back to back PWC to get tanks even close to safe zone.. As long as fish aren't too stressed then it's okay... If they're stressed, then do 2 separate changes a day.. Morning, night...it's so much work, but worth it in long run with normal levels and healthy fish..
