New CO2 tank & clean diffuser
I'm grabbing a new CO2 tank today and have my ceramic diffuser soaking to get it all nice and clean. This is my 3rd CO2 tank that I've gone through and I'm still not 100% confident when replacing. Since my diffuser will be running like new, should I tune down the amount of CO2 pumping into the tank and ramp up like the first time? I did this when I replaced the tank the first time, and it is a pain to go through the whole CO2 tuning again.
