The package recommends 2", but I like it deeper myself -- 3"-4". There's no max, really. (But too deep a substrate looks funny!) how many sqare inches will a 7kg bag cover? It says on the bag, but I forget. I bought seven bags for my 75 gallon tank (18" x 48" footprint). It wasn't quite enough, and I bought another bag. Eight bags of Onyx covered the bottom of my tank to a depth of 3"-4". Leigh http://www.fortunecity.com/lavender/halloween/881/ |

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". Leigh very big LOL Martin. |

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. "WD" wrote in message news:YQXga.240983$3D1.130586@sccrnsc01... "LeighMo" wrote in message ... how deep does onyx sand need to be for a suitable substrate? min, max? Make sure you rinse it well. I had a heck of a time. |

"Boris" wrote in message ogers.com... 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. http://www.thekrib.com/Plants/Fertil...lourite.html#0 http://www.thekrib.com/Plants/Fertil...ate-jamie.html "David Wee" wrote in message ...

rest. jtm -- Remove NOSPAM for email replies "WD" wrote in message news:ka4ha.4552$Zo.4528@sccrnsc03... "Boris" wrote in message ogers.com... Is onyx sand easier to wash than flourite?

As someone else said, let gravity and filtration do the work. You will have to change your filter media the first day or two after putting in the substrate, though. As for the chemistry, which I forgot to answer before...Onyx does raise your KH and GH. A lot at first, but it kind of wears off with time. Flourite, OTOH...though Seachem claims it's inert, many people have found it lowers the pH, at least temporarily. This effect wears off fairly quickly, though.
