Hello. Recently I have finished stocking my tank. It's overstocked currently with Juveniles. Last fish added in the previous 24hours. Last water change was 50% a week ago. Been holding off changing water this week as new fish was added and last was yesterday. Issue is the nitrate is rising and currently is at 20.0 ish........higher than I would be happy with even though I know they are ok up to 40.0 ish. Having spent a lot of money on fish in the last few weeks I don't want to lose any to water quality. Ammonia is zero and nitrites are zero. Should I do a partial water change tomorrow and the next day to get some of the nitrates out or leave it for a few more days and monitor the nitrates close. Don't want to stress the new fish with a 50% water change but don't want any to die from nitrates. Advice is appreciated
