I just picked up a kit today. Opened it up and I'm thinking the bubble counter and diffuser are a but big in relation to my 5 gallon tank.
I didn't buy the 20 Fluval kit after seeing the huge part in it, and it seemed to be reviewe poorly.
So, question then
Can I buy and replace them with something more attractive and smaller? If so what would be the best kind.
Also and tips of set up in my little tank, this is my first time with co2
