## Overview

Seachem Flourite Dark is a 7 kg premium porous clay gravel substrate designed specifically for planted aquariums. It supports healthy root growth without the need for laterite or chemical treatments, maintaining stable water pH.

Pre-washed but requires rinsing to remove dust, it ensures a clean, vibrant aquatic environment favored by plant enthusiasts.

## Description

Product Description Flourite dark is a specially fracted stable porous clay gravel for the natural planted aquarium. Its appearance is best suited to planted aquaria, but may be used in any aquarium environment. Flourite dark is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as Laterite are not necessary. Flourite dark is not chemically coated or treated and will not alter the pH of the water. Although it is pre-washed, because Flourite® Dark is a natural product, it will become dusty in transit and require thorough rinsing before use to remove any residual dust ( rinse until water runs clear through substrate). When adding water to aquarium, fill slowly to avoid disturbing Flourite® Dark substrate bed. Place a bowl in the aquarium and add water directly to the bowl, allowing water to overflow softly on to the gravel bed. Initial cloudiness is normal. To remove cloudiness, use mechanical filtration (such as filter floss). Use Clarity™ to accelerate clearing. Directions 1. Rinse the Flourite Dark in a bag if you have the 3.5 kg size. For other sizes, rinse it separately before use. 2. Mix Flourite Dark with other gravels if desired, or use it alone as an integral substrate bed. 3. No gravel modifiers such as laterite are needed.

Review: Wish I bought this in the first place. - I started out with sand - terrible mistake: it was so light that every bit of poo stood out; my ADF ingested grains as he tried to eat; and my plants weren’t thriving. I rinsed the Flourite for about 10 minutes and added them to my tank - it's 60l and this bag was sufficient. Everything immediately looked so much better. It’s a great chocolate color. Frog eating happily. Hopefully plants will thrive.
Review: ottimo, bella granulometria ed un bel colore ,purtroppo molto polveroso anche dopo un buon prelavaggio

## Questions & Answers

**Q: How does it taste?**
A: I haven't tasted it myself but my plants seem to really like it.

**Q: How do you clean this stuff on a regular basis?  I read some where not to use the handheld tube vacuum. ??**
A: Tube vacuum should work fine. I’d imagine whom ever wrote that hadn’t rinsed it very well and kicked up a ton of sediment. It’s really just chips of clay, nothing that should interfere with a vac any more than a gravel would!

**Q: Will my plants live with only this substrate?**
A: I have only this substrate in my 29 gallon and it is sufficient to grow plants.  I recommend periodically supplementing with Flourish in order to maximize plant growth, but a decent group of fish will provide enough nutrients for decent plant growth.

**Q: the description for this item reads 7k / 15.4 lbs but the item pictured reads half that 3.5k / 7.7 lbs; which is correct for the item?**
A: The container I received had 15.4 lbs., someone made an error.

### ⭐⭐⭐⭐⭐ Review
*by C***G on 25 September 2021*

I've used quite a few different Flourite varietes in a handful of different planted setups over the years. My most recent setup I used 3 different Flourites including this Flourite Dark. I used it as a "base layer" and put Flourite Black Sand over the top. The Flourite Dark isn't quite black and it isn't the muddy red that the standard and red varieties are. It's kinda... just... dark brown/mauve, I guess. It looks nice, but like I said, mine is capped with the Black Sand variety for a well, sandier aesthetic on top. I wanted a coarser gravel on the bottom to help anchor roots and a sandy top for a prettier look. I have a large variety of plants in my 55-gallon and all seem to be doing very well. Whether that's a direct result of the substrate, I can't completely say, but it's doing its job very well and the plants are rooting heavily in it and growing at insane rates. Don't expect Flourite to grow plants all on it's own; it takes light, CO2 and fertilizers to get proper plant growth. Having said all that, this stuff absolutely positively needs to be rinsed before use unless you want a glass box of mud water. I don't doubt Seachem's claims that it's pre-rinsed, but after it's been bagged and transported how-knows-how-many thousands of miles it bashes around inside the package and creates a bunch more dust. What I've found most effective with Flourite is that it should be rinsed in a sieve batch by batch. If you toss it all in a bucket and rinse with a hose you'll mostly just push the dust/mud to the bottom of the bucket where it can't escape effectively. Use a nice sieve and take your time, you only have to do it once (well, unless you have Multiple Tank Syndrome).
