Funny thing David,

I went for Flourite instead of Onyx sand because there were far more
carbonates in Onyx than Flourite.....GH/KH therefore increases and my
hardness values were hight enough.
Theres a complete trace element chemistry comparison of these.......now
where was it!!!!

Thinking....See these (after a quick internet search) - there was a better
one which compared loads of substrates.

The package recommends 2", but I like it deeper myself -- 3"-4".

that was quite funny when you pointed it out ;-).

But i will be getting myself onyx sand. Seems like the better
flourite from what i hear.

"I like it to be thick, and be laid deeply, at least 4""

Whoever thought gravel could be the source of sexual double entendre?
