picture example of c02 vs non c02 tanks these are 2 10 gallon tanks that sit right next to each other.
they both share the same 30 watt power glo bulb.
both tanks use play sand as a substrate.
neither tank gets ferts.
the tank on the left gets co2 via a ceramic diffusor. its placed in the front corner of the tank, not in the flow of the filter.
the tank on the right gets no co2.
the only difference between the two tanks, is that the one on the left gets co2. |
