Re: Gravel question
I've successfully used even the epoxy-coated LFS gravel that is only about
1.5" deep, but you can do *far* better than that. Flourite is my favorite,
but is somewhat expensive. I've thought that it seems similar to crushed
terracotta material, which probably isn't too far off since Seachem pretty
much says Flourite is just a "specially fracted" iron-bearing clay.
If your quarry gravel provides you with good growth than I see no reason to
not use it. I would probably put a 3-4+" deep layer in the tank. Tom Barr
recommended a depth around there to me some time back and I do think the
plants are happier with it. It certainly allows for a better root system in
the tank than a 1-2" layer would.
I've never added anything to the gravel besides some of Seachems plant tabs
myself, and I haven't even used those for a few years now.
