So I bought some HC at a local fish store and it is attached to a lava rock. It was in really bad shape when I got it but it is doing really well in my tank now. It seems to be pretty securely rooted on the lava rock and my question was what is the best approach of removing it without damaging it to badly? I want to plant it along the bottom of the tank to create a carpeting effect. Any input or advice would be much appreciated.
