![]() if done carefully (similar parameters as Aquattro suggested) a larger water change (50-80%) should go just fine. This is how I have done tank transfers in the past. Fill new tank 20% with old tank water then the rest with new water. As others have said, you don't want to be doing this on a frequent basis, but for a one or two off event for quick and short term correction purposes larger water changes are fine. A few weeks ago I did two consecutive 50% water changes in my tank to help flush out a treatment that I did on my tank.

![]() The Ceramic balls might be the cause of your nitrates... If you have room in your sump, you might want to consider sourcing a zeovit reactor, use the zeo media and go on the base system (Start, Bak, Food). It's a fairly proven system and well supported.

![]() Yup, I agree do two consecutive 20% water changes a week for the next month or until nitrates are in check, reduce the amount of food if it's crazy amounts, and I would also suggest getting yourself a phosban reactor and use some bio-pellets. I had very high nitrates then I put a bio pellet reactor on with the CORRECT sized pump for bio pellets and they went from 50-5ppm over 2 months. I now never have nitrates over 2ppm. Good luck.
