Currently I have an aquarium that has a pebble bottom. Smooth and round pebbles both big and small. I am toying with the idea of introducing live plants to my aquarium. I would like to avoid soil substrate. Will it be possible to grow live plants using just the pebbles?
One of the reasons for considering to have live plants is due to the fish poop that gets in the pebbles. I am hoping that these left over poop after siphoning will become fertilizer for the plants?
