Ultum Nature Systems Controsand Kona Aquarium Sand - Freshwater Tank Substrate for Live Shrimp & Planted Aquariums - Versatile 3L

I love this sand!! This is my first scape and I was very specific with what I had in mind. This sand is exactly what I wanted, a very natural earthy look paired with some red petrified wood. I have a 10 gallon rimless tank and the 3L bag covered it perfectly I have a little bit left over. I used a different substrate (fluval) to go inside the two cliffs to save sand. I didn’t rinse the sand and when I filled the tank it didn’t go everywhere or get cloudy at all. It’s super easy to move around.

I bought this for my shrimp bowl aquarium and love the look of it. It is easy to vacuum without losing the sand. It does get stirred up when adding new water but settles quickly. I wish I washed it better the first time as it took a few days to for the water to clear up. It was easy to put some plants and most have grown and done well. I would definitely buy it again

High quality rock. I love this company. I'll never use anything else. I love all their products.

I was hesitant about the claim that this sand does not need rincing but it is true. The sand gave off zero dust or discoloration to my aquarium. Comes in a variety of colors and grain sizes. I am now using it in two of my aquariums. Highly recommend!

Works well in my shrimp tank. I’ve had it for about and year and it still looks greats

Besides the plastic ring, painted broken porcelain and snail shells in this bag. Rinsed rock gently but always a light brown tinge to water. Put in bowl, added water, cloudy brown water. Left 24 hours to settle, only slightly less cloudy. Added filter, only minutely cloudy but as soon as any rock moved, very cloudy. Took all rock out, WASHED with jetted water and swirling motion. Non-stop brown cloudy water. Some kind of soft rock that dissolves when agitated in the least in this mix. Would never buy again. Going to buy polished rocks, then I know I can rinse and rocks will be clean. Total waste of money. Zero Stars.

Love it, it’s clean and looks great inside the tank, perfect product.

Normally i purchase the fluval black plant sand. This time i thought i would shake it up. I ended up ordering a second bag as the first one wasn't deep enough. Plus i increased from the original tanks i was goin to use. The sand is about the same in time it takes to runse it. It does say on the package to rinse. It is lighter than what the pictuers appeared on the website. It still looks good. I moved from California recently and was trying to bring that beach feel into the tank. Unfortunately, my light thay i ordered froam Amazon was delayed by three days. So i might have to go purchase ones. Since i planted my tank the night prior to the light arriving. Because of this the picture isn't the best view.
