Make sure you rinse it well. I had a heck of a time.

LeighMo - no offence but since you have just indicated that 'He' is an
innapropriate pronoun - you should be more careful with statements like.....

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?

Is onyx sand easier to wash than flourite? It took me hours to wash flourite
before using it in the aquarium.

The first few bags I didn't rinse thouroghly enough. The fine particles made
the tank totally grey, less than 1 inch visibility. I let it sit for days,
the stuff wouldn't settle. I tried filtering it out. The filters couldn't
filter out anything that fine, and didn't have any type of filters on hand
that could handle such. I ended up doing like a 500% water change all told.
I put the python in on one side with fresh water coming in, and put a hose
siphoning ou tthe other side. Let it go for about 2 hours.
The other 2 bags I bough I dumped in a 5 gallon bucket, put the hose in
and swirled my hand around until the water was well, not as bad. About 15
minutes. *Some* fines, so I'm told, make for a better substrate.

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.
