sera florenette A on top of or in the gravel?
according to the instructions of "sera florenette A", the tablets are supposed to be placed "in close proximity of the roots". I am not sure whether the tablets are to be put on top of the gravel or if I should push them into the gravel.
it does not matter; if you consider the tablets unsightly you can also push them into the bottom gravel!
