What defines a "Well planted tank" ? I have a few slow and a few fast growers. But how do i know its enough?
Fast growing plants are the beneficial ones when it comes to taking up nutrients including ammonia/ammonium. Stem plants are fast growing, but some of these need more light so it does not always work. One sure-fire fast growing plant are the floaters. Floating plants can take up vast amounts of nutrients and ammonia because they are close to the light and light is therefore sufficient, plus being at the surface their leaves can assimilate CO2 from the air which is 4 times faster than from water. So CO2 which is often the nutrient in least supply in the water is readily available.
Good floating plants are Water Sprite, Salvinia, Dwarf Water Lettuce, Frogbit, and of course Duckweed. Some of these are in our profiles (click shaded names). Some stem plants grow nice floating, Brazilian Pennywort is one, and there is Hornwort, Wisteria and Cabomba. Sometimes the latter three will not do as well.
Substrate-rooted plants can be low light, as the floaters shade them somewhat. And being low light, they are naturally slower growing. Swords are an exception though; they manage in moderate light and are fairly fast growing plants. The pygmy chain sword and chain sword are ideal in any tank due to their small size.
