Sulfur denitrator experiment

[Psyire]

I don't think you want to be increasing your drip rate...

You want a slow drip rate until you have enough bacteria to use up all the nitrate at that rate. Then you start increasing your drip rate slowly until you find the right rate for your current bioload. As your nitrate in the tank comes down you will further increase your drip rate until it is balanced at Zero nitrate in the tank, and zero coming from the reactor.
