    I have sand substrate in my tank, what's the best way to fertilize the sand besides root tabs?

    You could probably put in a plant substrate and then add the sand on top?

    Welcome to the forum and glad you joined us. I can't answer your question but others will. I use gravel. Alison:;hi2
