So on my new tank I will be using an in-line diffuser to remove one more item from the tank.
I've read contradicting ideas of where to place this, some saying the outflow, into the filter, and others saying the inflow back to the tank.
Obviously I want to ensure maximum co2 dissolving, so logic says put it in the outflow as it goes into the filter, as this will mix the bubbles into the water flow so much more before it returns to the tank.
However, I am just wanting to check I am ok with this? Putting water with high(er) levels of CO2 straight into the filter won't harm the bacteria in the filter will it?
