## Description

Seachem Fluorite Black Sand Substrate, 7.7lb

Review: 🌟🌟🌟🌟🌟 Black Sand – Turning My Tank Into a Showstopper! - I bought this black sand for my aquarium, and wow—my tank went from basic to breathtaking! It’s like my fish are swimming in a sleek, underwater penthouse. Why it’s awesome: Stunning Aesthetic: The deep black color makes everything in my tank pop—plants look greener, fish look brighter, and even my snails seem fancier. Soft & Fish-Friendly: The texture is smooth and safe, perfect for bottom-dwellers who like to sift through it. No sharp edges here! Easy to Clean: I expected a mess, but it rinsed surprisingly well and didn’t cloud my water. (Pro tip: rinse thoroughly, and you’ll be good to go!) No Fading: After weeks in my tank, it’s still as jet-black as day one. If you’re looking to elevate your aquarium’s look, this black sand is a game-changer.
Review: Love it vs. gravel - Love this stuff, so much better than the larger "gravel" for a tank with a side-mounted filter system. Keeps the fish poop from getting down in there and rotting because it does not come out. With this sand it instead stays on top and eventually gets its way over to the filter. Keeps the tank water in far better condition.

### ⭐⭐⭐⭐⭐ CLEANING METHOD IS IMPORTANT
*by D***N on May 31, 2022*

Yes, cleaning this is an undertaking. But if you want the beauty/benefits of high quality sand for your planted tank, that shouldn’t matter. The way I did this, and to minimize lost substrate, is throw everything in a large bowl. Then, beneath the bowl, place a cookie sheet or two of various sizes, nested within each other. Works best if the sheets have a dimpled/ribbed pattern. As you drain the water from the bowl, the cookie sheet(s) will act similarly to a gold catcher/sleuth. The heavier particles will collect in the ridges as the dirty water flows over and out. This will save a lot of the sand that spills over by nature. Simply collect it and return to the tank once water runs clear (while actively churning the sand).
