I will be brief and to the point. I currently have a 55g planted tank. i wish to increase the number of plants in it, but wanted to know if i should change my substrate prior to avoid the headache later on.
well, i know i will be adding Fluorite to the tank, but my question is, can i just add it on top on my current gravel?
i have some normal rounded medium sized gravel. I would prefer to carefully place the fluorite in the tank carefully with fish/plants still inside rather then removing everything and starting from scratch. has anybody added the fluorite on top of their gravel? Comments, suggestions?
