I have a 100g thats 48x20. I am thinking about 100 or so lbs of the the Hawaiian black, sound right?
 
Assuming you intend to have corals, ensure the sand is “reef safe” using those exact words.

Caribsea has a few black sands, and some of them use other terms like “fish safe” and will kill all corals within 24 hours. One of my close friends learned that the hard way and lost over $1000 in coral frags.

Crap! Are you serious? So if it doesn't say "Reef Safe" do you know where I can get black sand for a reef?

Caribsea also makes a reef safe sand. However, you just have to check. Make sure you’re buying the right product.

Otherwise, they have some black sand in Hawaii. Lol, but that’s outside my budget.

it even comes with a bio-magnet clarifier free inside the bag!
Lord knows I'm going to need that!
 
I dont like the sound of that, but i'm cautious. The term "reef ready" refers to if a tank is drilled or not. Personally, I need to see the term "Reef Safe".
 
LOL! You're not going to need that, but you can use that if you want. Still... it is very funny that you're having cloudiness issues as you receive this.

I dislike that people quickly get into the mindset of both blame and need. Doing so will put you on the road towards great stress and probable failure.

There's very little that you 'need' for a reef tank. Be honest with yourself. Instead of needing everything, and/or jumping to conclusions quickly, address things as "this product will help me with XXX. Do I want it?" If you're telling yourself that you need everything, you leave zero room for yourself to say 'No'. This results in dumping all sorts of chemicals and products into your tank, draining your wallet, and fluctuating your water chemistry resulting in the death of livestock. If you're able to say 'No' 95% of the time... then your wallet will be protected, your chemistry will have a chance at becoming stable, and you'll be likely to have greater success and enjoy the hobby for a long time. =]
 
Awesome @york1 has experience with "Caribsea Hawaiian Black Sand"... if that's the exact name of yours, you should likely be good to go!
 
I have never used black sand. But saw on BRS that some black sands are very magnetic due to their volcanic origin. They showed a video of it collecting on a powerhead magnet.
 
I have been doing this a while and I had not heard of that either. Then I saw the video and you were mentioning the magnetic clarifier. You never stop learning in this hobby.
