Review: Another great product from Seachem - Great inert substrate if you don’t want to alter your water chemistry by using substrates like aqua soil etc. Can’t speak to its utility for planted tanks as I’m using it in a sparsely planted shrimp breeding tank. Incredibly dusty so be sure to rinse thoroughly before adding it to aquarium. Rinse in a bucket until water runs clear and be careful when filling aquarium not to disturb it.
Review: Ripped bags but great quality. - I bought 4 bags and every one was ripped. This didn't happen in transit as one of them were taped up. I'm not weighing them to make sure I got what I paid for but I did lose a lot inside the packaging. My husband is very happy with the product. He knows it has to be rinsed very well before he uses it so there are absolutely no issues with the quality of the product. 10/10 would recommend and buy again.

## Features

- GRAVEL: Seachem Flourite Black 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 freshwater aquarium environment.
- AQUARIUM BED: Gravel modifiers such as laterite are not necessary when using Seachem Flourite Black as this product is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels.
- SET-UP: When adding water to the aquarium, fill slowly to avoid disturbing Flourite Black 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, but to remove this simply use mechanical filtration
- COMPATIBLE: Flourite Black substrates will work fine with an under gravel filter and will not soften or decompose to an unsuitable state within your tank.Flourite substrates will work fine with an UGF
- SAFETY: Seachem Flourite Black is not chemically coated or treated, thus does not alter the pH of the water. Flourite Black is beneficial for the life of the aquarium and need not be replaced.

### ⭐⭐⭐⭐⭐ Another great product from Seachem

### ⭐⭐⭐⭐⭐ Ripped bags but great quality.

### ⭐⭐⭐⭐⭐ Looks good works a treat (wash,wash,wash)
*by C***D on 19 November 2023*

Amazing quality but rinse very well until no cloud or murky water. Great for shrimps tanks to help them contrast against the substrate. First time using the product recently and I’m adding to all tanks to enhance my aquascaping attempts. If you have Corey or other bottom feeders, you may want to use sparsely and still have sanded areas for those that nuzzle subrate for food. Easy to gravel vac Highly recommended, any questions just ask
