I like this, gonna be setting up a 70g.
I'm trying to glean as much info as I can.
How does this sound, Special kitty as a base, on top of that play sand, for the final topping, gravel that I have from the old set up.
Sounds good to me, I just cap it with play sand from homedepot and let the tank run it's course. Of course I follow EI dosing for fertilizers, but my plants are healthy with good strong roots.
