Root tabs or fertilized substrated for carpet plants?
I have to pick up the substrate for my future tank, which will have several carpet plants (Hemianthus Callitrichoudes, Staurogyne Repens). I have 2 options:
1) Fertilized substrate (Dennerle DeponitMix) + Quartz gravel 1/2mm
2) Quartz gravel 1/2mm + root tabs
What i fear about fertilized substrate is the possible mixing with the gravel in case of change to the layout or replating of some plants, so this makes me lean towards option 2. But my concern is that root tabs won't be as effective as the fertilized substrate.
What do you think? Can the root tabs perfectly substitute the fertilized substrate maintaining the same effectiveness?
