Water column NO3 excess can be solved by adding essential plant elements assuming there are plants and the rest by denitrification. Denitrification can be done by filling a canister filter with BBQ lava rock over one inch in diameter. This can remove several ppm of NO3 a day while not changing other water parameters unlike the materials in the video.
