I currently have eco complete in my 55 gallon tank. I've kinda tried growing micro sword grass in it. It doesn't grip very good and every time I do water changes, it's floating all in the tank. I wanted to add sand over the top layer to give the grass finer subtract to grab to. After reading reviews, I saw a lot of good things about black diamond. Cheap and things grow good. Only downfall is rinsing the oily film .

My brother used to have bearded dragons in a small 10 gallons tank. after around 3 months, he didn't enjoy the responsibility of cleaning the tank. We donated them to petco.

So with a spare tank laying around, heater, light and air pump, I decided to test out the sand.


So far I have rinsed the sand, let it sit and rinse again. I did have the oily film on mine.

I poured it into the tank, very cloudy so far so I'm wait for it to settle.

Also it's not very good for building up ground. I tried to make a little cave but the sand it very heavy and silky. Maybe mixed with eco complete, it will do better.

If I had to guess about the oily film, I would say it's something to keep the sand sleek so it can flow through the sand blaster without clogging.

Very easy to plant in. Held everything down with one try. Even the small micro grass. Still cloudy though

It's been a few hours... still a little cloudy. I might have to hook up my small filter to get the water clean.

Still hasn't cleared up. I also put it in my 16 gallon hospital tank. It has a small guppy, snail and ghost shrimp. It doesn't appear to be harmful.

In two of the three tanks I have it in I didn't rinse it and I just put it straight in the tank. One of those is my 75 gallon planted which already had completed it and fish. I proceeded to dump in a bag and a half while re-aquascaping it. The fish have had no harm and the angels actually spawned not a week later.

The other tank I added fish to immediately and has no plans but has had no ill effects to the fish they were put in it after it was set up with the black diamond sand and does not appear to be creating the brown algae that is a common thing with silica sand.

The other tank I rinsed but none of the tanks have had a Clarity issue really at all.

I left it in over night and all day. Still a little cloudy, but clearing up. I think it's beautiful sand. Has almost a sparkle to it. From what I heard, it's good for the plants cause it coal. And at that price, it's cheap to replace. So over time, if some is sucked into the gravel cleaner, you can top it off under 10 bucks. Probably the on cheap thing in the hobby lol

it is coal slag a byproduct of making coal, which is why it is heavier than standard sand, also it has dust and particles straight out of the bag so it is best to rise it 2-3x before putting it in a tank. look in my sig at the 75

Planting in this stuff was a breeze. Even the smallest of plants stuck with no trouble
