These plants are all submerged. Photos were taken when the water was drained during a water change.
Most (if not all) people would agree that you'll grow healthier plants with CO2, not just crypts. C bullosas are usually found in fast flowing streams. Having good water flow or currents in your tank also help distribute/diffuse the CO2 evenly. There are vitrually no dead or stagnant spots in my tank. I have two eheim canisters and two needlewheel pumps for the CO2 diffusion and I can see tiny CO2 bubbles in every corner of my tank. Even though I do not fertilize my tank, the plants do get nutrient from the water column from fish waste. I have a group of cardinals that are fed daily.
