Need a quick awnser please.another question!
Im doing DIY Co2 for a 48 gallon. I have 2-2 liter bottles I will be diffusing it with an airstone up into my HOB filter. My question is should I start both bottles now or wait how long apart? One other thing is Whats the best mix to use and how often should I change?Also do I have to have a bubble counter with DIY? Thanks!
