rodri075,
Awesome tank, extremely clean. I notice you are using a skimmer on your tank, which I am assuming contributes to the cleanliness of your tank. I was told not to run a skimmer on my nano w/ zenia in it because the zenia liked slightly nutrient rich water. Any comments on that thought? My zenia is doing well so far, but I am thinking about running a skimmer anyways to help remove particulate matter in the water column. TIA.
