| | Emersed growth of plants - external fertilisation
I believe that many aquarists are growing emersed plants to help with removal of excess nutrients from their tanks. I do the same with Pothos, however I think that it could do better. I have quite a big amount of plants in the tank, for which I add micro nutrients every day (just so they don't show any deficiency). I think, that this amount is not sufficient for Pothos and it probably competes with other plants. I would like to avoid adding more fertilizer into the tank, so got an idea of using additional container just for Pothos with higher levels of micro nutrients. It should work like this - Pothos will gain macro nutrients from the tank water (they are abundant with ~25ppm of NO3 in tap water), but it will take most of the micro nutrients from a separate container.
Anyone tried it before already? Any comments if it's worth the try or is it a complete waste of time?
A quick photo - the end of Pothos with already established roots is in the tank and I weighted down the stem with a small stone in a separate container where I added a bit of micro fertilizer. I've just set it up, so there are no roots on the stem (and maybe never will be).
