    im in the process of setting up my new 75gal tank . I bought 3 bags of 'premium' black sand substrates and I tired to rinse it before I place it in the tank ... but it's like the 10th time of rinsing and the water is still very dirty and black/grey ?! Is it normal at all ?? I don't want to poison my future fish !!

    You're much better off getting Black Diamond Blasting Sand in my opinion. It's very soft, super cheap (don't know what you paid for this stuff), and pretty easy to wash. The only reason I could think of it giving you problems is if you're trying to grow high maintenance plants.

    It shouldn't poison your fish. Just put it in the tank and it will settle.

    Just keep rinsing. I go on length of time versus actual repeated rinses. I found that it takes at least 30-40 minutes for that sand.

    I would let it sit for about 15 minutes. See if it settles. Is it superfine sand? Or is it more of a medium grit? The super fine sand will cloud up very easily.

    What brand is it? I have National Geographic Aquarium Sand from petsmart. I rinsed it. When i put it in the tank the water was black and there were little clumps of sand floating. I swished it with my hand and the floating clumps fell to the bottom. A little over an hour later the water was clear again. The filter was off when i put it in but i turned it back on after i knocked the floating pieces down.

    I have the same brand as you. I used a garden hose to agitate it well and it took about half an hour. I put in in the tank, let it settle about 2 hours then turned on my filter. I also stuck a sponge filter on my intake the first couple of weeks just to protect my motor. It was pretty clear within a day or so and very clear within a few days.
