Product Description

FLOURIT BLACK: Seachem Flourite Black is a specially fracted stable porous clay gravel for natural planted aquariums. It looks best in planted aquariums, but it can be used in any freshwater aquarium setting.
AQUARIUM BED: Gravel modifiers like laterite aren't required when using Seachem Flourite Black as an integral substrate bed; however, it can be mixed with other gravels.
SET-UP: To avoid disturbing the Flourite Black substrate bed, slowly fill the aquarium with water. Place a bowl in the aquarium and fill it with water, allowing the water to gently overflow onto the gravel bed. It's normal for there to be some cloudiness at first, but you can easily remove it with mechanical filtration.
FLOURIT BLACK SUBSTRATES ARE COMPATIBLE: Flourite Black substrates are compatible with an under gravel filter and will not soften or decompose in your tank to an unsuitable state. The use of a UGF with a fluorite substrate is fine.
SAFETY: Because Seachem Flourite Black is not chemically coated or treated, it has no effect on the pH of the water. Flourite Black is good for the aquarium's longevity and doesn't need to be replaced.

Questions & Answers

My loach enjoys digging and poking his head out of the water. Is this a smooth or a rough surface?

This is a piece of gravel. Instead, I'd suggest using soft sand with loaches.

Is it possible to use gravel with this? I'd like to use this as a base layer, then add gravel or mix on top. Is it possible for me to clean it with a vacuum?

yes; I didn't mix with gravel in any way; I simply laid down a one-inch layer at the bottom before covering it with gravel. My plants are in excellent condition.

I'd like to use this as a substrate, but I prefer the look of white sand. Is there a white version of this, and if not, would I be able to cover it with white sand?

It'll all end up mixed up in the end. I would purchase the white sand you desire and then fertilize your plants to keep them healthy.

Selected User Reviews For Seachem Flourite Black Clay Gravel - Stable Porous Natural Planted Aquarium Substrate 15.4 lbs

Pie in the Sky! After weeks of reading reviews and researching this product, I realized that the most important thing was to cure it under the sun, rather than rinsing the living crap out of it
5/5

So that's exactly what I did, spending less than 15 minutes total to raise my three bags and end up with a fantastic, cloud-free tank. br>br>I poured one of the bags into a 5 gallon bucket that was halfway filled. As you can see from the photos, the resulting goo is not something you would ever add to an existing tank, let alone a new one! I emptied the bucket and refilled it halfway with the clay soup mess. I did that about 5 more times until the water was 90% clear and then I did that about 5 more times until the water was clear and% I did the same thing with the other two bags, then spread the Flourite out on a fitted sheet. br>br>I should mention that if I had wanted to, I could have easily continued rinsing until the gravel was completely clear, but I didn't. In any case, I emptied it into two buckets after about three hours in the sun. The Flourite was dusty because it was bone dry and contained a million tiny particles. To keep the dust down, I poured about a gallon of water into each pail before placing it in the tank. I then started filling it up five gallons at a time, pouring the water onto one of my tank's rocks. There was no cloud when I added my plants, despite all the rustling of the gravel to get them rooted. Yay!.

I prefer UNS Controsoil to Seachem Flourite for planted aquariums because Flourite leaves a foamy residue on my aquarium glass and a murky cloud all along the aquarium floor, even after rinsing
3/5

I ended up draining all of the water and rinsing the Flourite once more, and a small amount of residue is still visible days later. I much prefer Ultum Nature System's Controsoil (shown in the second photo), which does not require rinsing, has very little clouding, and retains its rich black hue once submerged. Overall, I consider this to be a waste of money, and I recently purchased another bag of Controsoil to replace the Flourite.

I had no problems with the water becoming cloudy because of this product
5/5

I'm not sure if I struck it rich, but I bought three bags for a 29 gallon tank (but only used two). I worked with one bag at a time and did the following: br>br>In case it helps anyone, I worked with one bag at a time and did the following: br>br>1) Drill a total of 2 dozen 3/16" holes in one area of the lid, primarily near the edge. (You can use any size that is smaller than the majority of the flourite. ) It would also have been faster if there had been more holes; It's possible that having fewer people would not have been a problem. I just kept drilling holes until I was satisfied). br>2) In a clean 5 gallon bucket, I added 2 gallons of tap water and emptied 1 bag of Flourite. br>3) Put the lid on and make sure it's well sealed. Gently agitate it; The bucket swung from side to side as I swung it back and forth. 4) Gently pour the water out on the side. br> Taking the lid off and slowly pouring it onto the lid allows the water to drain through the holes and into the ground. I liked pouring onto the lid because it meant I wouldn't lose it if I spilled it. Fortunately, this did not occur. br>5) Repeat steps 3 through 5 with 2 gallons of water. 4 until the liquid is mostly clear. In my case, it only took four washes in total. br>6) The Fluorite will be damp at this point. Pour it into the tank that you're going to use it in. Then, using your hands, a paintbrush, or a spatula, spread it out evenly. It doesn't have to be perfect because it will be displaced when the water is added. br>7) I half-filled the container with water before adding it. A 5 gallon bucket was filled with bath tub tap water. When it was finished, I went to pour it into the tank and put another bucket to fill. br>8) I flipped an empty dog bowl upside down in the tank and slowly poured water into it. br>9) I took the bucket that was filling in the tub and set it aside while I poured the second bucket into the tank with the dog ball, as described in step 8. I kept doing this until the tank was completely full. br>br>In my case, it took about 2 hours to settle, and I hope this information was useful. I'll try to update it once I've planted the tank and seen how it grows.

Love it! In my aquarium, it looks great
5/5

I started by poking holes in the bottom of the bag and placing it in a bucket to rinse it. I decided to bake it in the sun for 3 hours after reading other reviews, and there was barely any clouding of the water. I've attached a photo taken an hour after the water was added. I'm very happy.

Great Substrate, no need to be concerned about the cloudiness that many people complain about
5/5

Almost every negative review of this product mentions how filthy your water becomes as a result of using it. There is a straightforward solution. My new tank was crystal clear 24 hours after I filled it with unwashed Flourite Black. br>br>Open the bags and pour directly into an aquarium that is empty. Before filling, lay out all of the rocks, fixtures, decor, and plants. When it's time to fill the tank, you can't just turn on the hose and pour buckets of water in. Instead, use a hose to trickle fill onto a plate, a small bowl, or a large rock to disperse the water flow and avoid disturbing the substrate. Pouring water into the tank was something I did with a pitcher. This takes a little longer, but it's a lot less work than repeatedly rinsing this stuff in a bucket, only to discover that the water is always cloudy when you're done. You'll still have cloudy water, but all you have to do now is run your filter for 24 hours and then add the magic secret (though you could probably use it right away). I had to wait until the next day for Amazon to deliver it). API Accu-Scan was the tool I used. Clear. It costs around $8 for an 8oz bottle on Amazon, but only 1/2 cap is required. To treat a 50 gallon tank, fill the bucket halfway. If you prefer, you can find a variety of other aquarium clarifiers on Amazon from different manufacturers, but I can only recommend API because it is the one I used. br>br>After 20 minutes, your tank will be crystal clear. Its effectiveness can be seen in the photos attached.
