Here is another video in my continuing conversation about Nitrates in your Fish Tank. (Freshwater Aquarium)
In this video I explore the idea that Nitrates accumulate in the substrate and will only be significantly reduced if you do a thorough gravel vac along with a water change. 
Watch the video to see my findings.
I created this video with the YouTube Video Editor (https://www.youtube.com/editor)
