But the important thing is you must have a heavy plant biomass. This means your tank is fully covered in plants. If you have only a few plants in the tank, then regular tank maintenance still stands.
okay sounds good, you have informed me well on this topic, thank you very much ill be starting my planted tank this coming week, hopefully it turns out, if there is any other warnings / suggestions let me know. NEVER gravel vac?
