I’m not a scientist therefore not disciplined in proper testing procedures but if purpose to establish how this occurs in an aquarium environment then doesn’t maturity of that environment matter. Are the tests going to extend years into the future as mature media might behave differently than that which is new and will different media be used. My understanding being that contact time affects amount of DO left post nitrification therefore that which has prolonged contact time might behave differently as to how biofilms a few centimeters in respond vs several father down the path that molecule of water must travel. Might turn out that deeper down that corridor that molecule of water travels the ratio of N produced might be considerably lower vs that removed than the 7:1 per the study quoted.
At least that’s how I understand it. Something needs to reduce/remove DO plus a carbon source to facilitate denitrification. Unless all biofilms behave the same regardless how much actual DO exists outside them.
