It appears there are pros and cons with your choice of sand, but the fact that it is magnetic is expected and not necessarily of immediate concern. You may still want to remove it after reading the reviews though. In the short term, I wouldn't panic :) Dan

+1 and you can always add reg sand as well later

You have a three week birthday celebration??? Oh to be young again!:mrgreen:

LOL I wish. No just the one night I have free. The rest is busy busy busy.

It shouldn't take too long to remove the sand, if you ever decide to put something on the bottom, why not use aragonite??

I prefer aragonite to sand because it doesn't pack down and trap gasses and because I don't like the bb look. Just use enough aragonite to cover the bottom with a thin layer, another option if you like the black look, I believe Jl sells the black equilevelent of aragonite. My friend used it in his 90 that has been up for 2 years and still looking awesome, got some coraline on the substrate now. Reminds me of a volcanic reef.

well I have had a few PMs on here and 3reef from people who have used this sand in their tanks for years with no problems.. so I'm kind of on the fence ATM..
I would like to see conclusive evidence that its either bad or good, it is magnetic, but not all of it. so the only issue I see so far is I cant use a magnetic cleaner. but obviously if its a harmful metal it could pose other problems in the future. this is why I am skeptical, as people say its fine and some say get it out. :question::question:

I wasn't referring to the black sand but rather the black substrate which is larger granules, looks awesome!

If your worried about iron in your tanks, the one pet store I worked at had no less then a dozen rusting razor blades in their system when I finally cleaned out the entire thing. I doubt they had any effect on the tanks. When I removed them everything was the same.

well its volcanic sane so would it be iron? its hard to say what type of metal is in it.
