Flourite Red 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. Fluorite Red 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. Fluorite Red is not chemically coated or treated and will not alter the pH of the water. Fluorite Red is good for the life of the aquarium and need not be replaced.
Set-up: Although it is pre-washed, because Flourite Red is a natural product, it may become dusty in transit and require rinsing before use to remove any residual dust. When adding water to aquarium, fill slowly to avoid disturbing Flourite Red 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.

All non-painted aquarium substrates need considerable rinsing before use. Flourite requires a bit more time to settle before the cloudiness disappears because it is a clay-based product. Clay produces a much finer and lighter particulate dust compared to sands, calcium-carbonate based substrates, and gravels. Clay particles are also more easily scratched when shifted around (such as when stirring them in a bucket to rinse them). This is one reason why this product appears to never rinse clean (because many people use a washing process that actually generates more dust as they're rinsing).
Seachem makes a sand-grain version of this product which I used to use. In my personal experience I found the sand to be harder to plant in (plants without well-established roots would tend to slip out of the small-grain substrate), and found the sand to be more vulnerable to compaction and anoxic conditions. The benefit of the sand is it's softer on the barbells of bottom-scavengers and burrowers like cories, loaches, etc.
The reasons I don't give this product 5 stars:
As a nutrient source, this substrate is virtually useless... No macro-nutrients, and most of the micro-nutrients are locked in an insoluble form, useless to your plants. Note that most plant-specific aquarium substrates fall short in this category, as aquarium substrates aren't developed to act like garden soils.
The clay-base for this substrate is baked... On the one hand, this makes it MUCH easier and less messy to work with, on the other hand it greatly reduced cation-exchange-capacity of the substrate (which is really what makes flourite work as a plant-specific substrate in the first place).
In short - there are better products on the market, but you will pay an arm and a leg... Flourite falls short in some respects, but they're mostly necessary compromises in my eyes...
Oh, and my bag had a hole in it when it arrived, so I'm not thrilled with that... Plus Purolator shipping... So that sucked.
"Rinse" is not sufficient for this product, you need to heavily wash and sift this stuff. It took me hours to properly separate the very fine dust from the large flakes; it was a messy process that took a lot of work.
I very much like the product but I just want to let you all know that the directions on the bag are very misleading about being "pre-washed" and needing a "rinsing"; Installing this substrate properly with out headaches is going to take a lot of effort, my hands are cut up from turning the substrate over and over during washing, little pieces are embedded in my hands from how much labour was required.
Final product installed looks amazing, I know the plants are going to love it.
1. RINSE BEFORE PUTTING IT IN!
2. Read number 1
3. RINSE AGAIN!
So many bad reviews because people are too lazy to properly prepare the product before putting it in. Come on!
Great inert clay gravel, holds ferts and easily cleaned with a regular grab vac. Great product.
*For some reason, my bag from amazon came with little strands of plastic mixed in the bag.
