Is it necessary/better to run an airstone at night with diy co2? I only worry about it during the first couple days after starting a new bottle since bubble production is so high.
Was wondering what others's thoughts are...
From what I have read it seems it depends on how many fish you have in the tank. For if you have a lot they need an airstone to provide more air. Thus if, with DIY Co2, the fish start swimming at the top you need an air stone.
Since I only have 3 fish in a 20G H tank I am not using an air stone when I have DIY Co2 running.
