I have hard water and high ph (8.4). My Amozon Sword grows out of control putting out new shoots and taking over the whole aquarium if I keep root tabs in the tank. If I don’t it does just what yours is doing. When I give them the root tabs I just keep them pruned to the size I want them and I can get enough New shoots off of them to fill multiple other tanks. When the leaves get to tall for the tank I just pench them off to make room for new ones to grow.
That is good to hear! My water is from a well and it is hard with a high ph as well. I’m going to give the root tans a shot and see what happens.
