HI all,

another newbie question..

I keep reading references to fluorite substrates for plants. I've read
through the FAQ and couldn't find the benefits.

can a kind soul care to educate a newbie on this obviously common knowledge
item? Right know I have pea-sized gravel, but I probably need to add a bit
more substrate material to increase the thickness.. so might as well add
something that is more beneficial.

thanks for any info.
