water change in New to the Marine Aquaria Hobby Posted January 3, 2005 My NO3 is high. I did about 70% of water changed. Is it ok? I also put in de-nitrate, lessen feeding to twice a day for my 7 fishes, change my filter wool, upgrade my skimmer to Micro AS-300p for my 3feet tank. Will these help? Thank you.
