I have very high nitrate, 50 ppm, despite very good growth of Chaeto algae as you can see in the picture.
The quantity of the Chaeto in the picture should absorb a part of the nitrate.
The only change I did was to add PhosBan for two weeks ago.
Could it be the cause of the rising of nitrate??
The aquarium is about 6 years old and volume is a bout 158 gallons.
Any idea?
