    Ohh I see thanks for the advice wish they would warn that with the sand . I love the look of it but I will just go down the special grade route I think take out 20lb at a time

    That's pretty interesting. I had set up a 30g fish only tank in the past using this same black sand. After cycled I've added a small school of green chromis, two fire shrimps and 6 turbo snails. Within 12 days everything was dead. Could not figure it out the reason why I lost them all (had three other saltwater tanks at the same time, the smallest being 55g), I ran polyfilter and tested for copper just to find out that my copper levels were super high (6ppm). Never used this sand back again.

    looks water changes will be in order and the resulst are overall not bad as it also does point out areas for improvement, some related to water changes and use of carbon and dosing

    Kinda makes me wonder if it's something that's happening because of improper maintenance of the sand bed? Or something else? There must be a lot of people using it without a problem. But there are also a lot of people using it with problems. Maybe something going on causing the metals to leach. It IS magnetic after all. Everyone that is having problems has the same metals coming up high in their ICP test. That can't be ignored. There are plenty of posts about it. It's not one person that is experiencing this. I'm personally in the process of removing the black sand. I will not be able to get it all out without tearing my reef apart. But I will get a good part of it out. I'll be replacing it with Carib sea special grade.

    I think just not alot of people use black sand in a reef, so there isn't as much anecdotal data on it. ICP tests are fairly recent, so suddenly we have something on it. Generally the wisdom was to only use it in fish-only tanks, not reefs, because you want the light reflection from the bed. (I know it's not actually alot, but this is what people say).

    I wanted it for mine, but the expense was too high. It's funny how now that we have ICP, all kinds of weird data comes to light.

    Scooped out most of the sand. From the front. Can't get to the back, maybe with a small siphon at a later date. Put it in a bucket a little bit at a time and went through it. Mostly looking for my cerinth snails. Whatnot noticed is it was pretty much devoid of life. No worms, nothing. It's been in there almost 2 years now. I did add some white sand about 8 months ago. It was mixed up pretty good. On a good note I have found some shrimp molts in my filter sock. Been doing 10% water changes and running rox carbon since I got my ICP results.

    I had the exact same experience with my black sand. I removed it and did a series of 30% water changes and just now have acceptable ranges for nickel and vanadium.

    How long did it take to get acceptable ranges?

    It took me six months. I documented it in my build thread. No fun.

    I'm actually curious. You say the sand was devoid of life. Are the rocks? Like do you have bristleworms or pods or anything on the rocks, and just the sand is dead, or is the whole tank without pods/mini cuc/etc?

    I have pods on the rocks. Not as many as I used to. Actually never saw a bristleworm in this tank. Snail population has been slowly dwindling. About 4 months ago I had cerinth snails lay eggs on the glass. Hardly have any left. I just ordered more snails. Lots of burrowing snails. New sand in the front. I'll work on the back slowly. That's going to be a pain. So yeah sand was dead of life.

    Interesting.. that lends credence to the theory that the sand is the killer/leecher. If pods were on the rocks but not the sand, they were further from the source of bad...
