Just Toby;4138666; said:Test the tap water, if the tap water is lower then it is a simple case of regular twice weekly water changes to dilute the problem.
The good news is that your filter is working correctly.
If the water out the tap is above or similar to 50ppm then you need to look at nitrate reduction techniques such as ion exchange resins or algae scrubbers.
Let us know what the tap water is like and then report back
