Flourite, 7 kg / 15.4 lbs

...if you rinse well it's not as bad as some of the reviews. I'm very happy with this type of substrate. I had gravel in my 3 tanks before I discovered this stuff, and the gravel was so dirty and my plants weren't thriving. I bought flourite black and was afraid even after rinsing many several times in a half hour that it would murk up my tanks. I put all my fish and plants in a giant plastic tote with their filter/heater/decor for a couple weeks while changing substrates and cycling again. The murk went away pretty quick, I had clear water within an hour. The way I rinsed: Dumped 1/2 bag of flourite in a large bucket. Rinsed by filling bucket with water over substrate and BLASTED IT with the hose until I filled the bucket with water. Let substrate settle to bottom (some flourite may blast out but it's an insignificant amount, in my opinion) then let water drain almost completely.... Then repeat this about 10-15 times or until it's only slightly murky. Dump in aquarium and fill with water as usual and set up as usual. After planting live plants and blulbs of water lily & water onion, and another type of seed in this substrate, I'm convinced this is the best substrate for my tanks. The bulbs I planted in this substrate that would not grow in the gravel are thriving in the flourite, they look beautiful. It has not clouded up anything and it looks more natural in the tanks. You can also see the fish scale color is much brighter against the natural and dark substrate. I bought this clay colored kind for my red claw crab/guppy tank. I haven't planted this one yet but I will update with pictures in a month or so. The pictures posted right now are with flourite black. Another thing about this stuff is: there are larger pieces and smaller pieces. I thought it would be more sandlike but I actually like it better than some other actual sand substrate. Just thought this might be nice to know in case other buyers expected it to be more like sand. It's actually small clay pieces. Your aquatic plants will love it! **update** 2 days later: So I wrote a review a little early for this flourite... Yesterday I almost came back to leave a 1 Star review... But I'm going to leave it at 5 because even though the dust was BAD with this red clay substrate compared to the black clay... It took 15 rinses with a hose outside and then I added it to my tank and filled with water... It was fully murky for 24 hrs. I put my decor and plants the filter in to help and ended up taking everything out after the 24 hours and rinsing everything off (it was covered in red dust/sludge).. Draining all of the water again and then refilling with water. Be sure to put a bowl with tall sides in to pour the water directly into the bowl so you don't disturb the substrate as much as possible. Let the water sit with NO filter going for a few hours and then let it run overnight with the bowl under the water flow if you have a filter that drops water). Then do not to disturb the substrate again when placing your decor... I placed a large abalone shell under my filter to keep the substrate from getting pushed around. (I know... Pain in the A but... Look how natural and beautiful my tank is!!)... Anyway, if you don't mind a little work for an amazing substrate with great results of you keep a planted tank... This stuff is really worth it. I probably personally will never buy this red stuff again but the black stuff is great... Low dust and the plants grow like wild in there! My crab seems to like it as well! My first two pictures are with the black flourite and the second two are with the red, as you can plainly see.

It definitely needs to be rinsed before use. The fish and plants are thriving, and the overall look is amazing. An excellent substrate for planted aquariums—great quality, a natural look, and plants root beautifully.

I purchased 5 15.4 bags of flourite to put in my 75 gallon turtle tank so I can put some aquatic plants in there soon. I undertook this a few days before Christmas, and I'm still recovering from the ordeal. While I do think the product works well for planted tanks, I think there should be incredibly good instructions provided. It says you "may" have to rinse it, but no matter how much you rinse, it still releases extremely fine red dust in the water. I did a whole lot of research before deciding on this product, and on how to put it in. I suppose, for a fish tank, just letting the sediment settle at the bottom is ok. I have turtles, and they disturb the substrate (even under river rocks) so I didn't want a red cloud every time they played and explored. I read tons of blogposts and watched tons of videos on methods for putting flourite substrate in and decided to trust someone that recommended to let my canister filter take care of it with filter floss. BIG MISTAKE - DO NOT EVER DO THIS. Immediately the tank was like thin red paint. I was worried, but had faith the canister filter full of filter floss would handle it. I let it run until the water was clearing up, took the filter outside, rinsed everything well, set it to run again and disturbed the substrate to get all the sediment back up. I repeated this for several days to no avail. There was just to much (extremely fine) sediment. I finally found a video on a method where you fill a 2-liter soda bottle with dry (or rinsed substrate) then place the bottle in the aquarium until it is submerged and filling with water. As soon as it's about to be full of water (or all the air nearly all bubbles out), turn it over (upside down) and let the substrate fall out. The remaining air will cause the sediment to bubble up while the rocks trickle out, sort of cleaning them off of the dust one them, and 99% of the sediment stays in the bottle. I did this after completely draining my tank, taking all the substrate out, taking the tank outside and cleaning it so I can set it up again. The sediment is like powered paint and once it's wet it's a HUGE MESS. This coke bottle method is BY FAR THE BEST WAY TO DEAL WITH FLOURITE. I just added a bottle every time the water cleared up and disturbed the substrate until there was no more cloudiness. It's been a couple of weeks and dealing with this has exhausted me to to the point where I don't want to act on my inspiration for aquascaping and adding more life (plants, fish and crayfish) to my tank. Doing it the wrong way really messed me up, but the instructional "may need rinsing" is totally misleading. I will take only 1 star off because my trouble was primarily my own fault (though there's no help from Seachem so it's practically unavoidable) and the small plant I put in seemed to take well. After I plant my tank I will post pictures, in addition to those I post now of putting it in, etc.

This substrate has a clean, nice natural look. The material is chunks of clay and minerals. Supports a great biofilter and seems to be just right to buffer the pH and maintain mineral hardness (GH and KH). Never vacuum it and instead to large RO water changes each week. If you are adding this to an existing tank or there is livestock in the tank, you should wash it first. Rinse it and agitate it until the runoff is clear, then mix it around and rinse some more. Use a strainer with small holes. This substrate gets very dusty during shipping and if it is not washed your water will turn red and the TDS will skyrocket and may injure any livestock. That said, if you don't have livestock there is no need to wash the substrate and it's probably better not to, because it is good to have a diverse mix of particle sizes and washing the substrate removes all or most of the smaller sand like pieces. The finest particles will settle to the bottom of the substrate and add surface area to the biofilter, which will filter the finest pieces of detritus (fish and plant waste) as it settles downward. The beneficial microbes turn the detritus into dissolved nitrates which you remove by doing large water changes and having plants that consume it. Again, this is without ever vacuuming the gravel. Water testing for ammonia, nitrate, nitrate, GH and KH, is of course recommended.

Is a bit more black than brown. Is hard to wash some dust, but then you have a viable long term aquarium solution for fish and plants. This is a natural media with small and medium bits. It settles and stays put, due to it's weight. Unlike processed sand and gravel, there are no dyes or sharp edges to cut the catfish. Until I see a product better, this is worth every penny. Don't mess with HD sands, or pea gravel. Sand cuts your bottom fish, and gravel lets material settle in where fish can't reach it. This is natural and my plants root fast in it. To wash your flourite: dump one bag into two handled shopping bags, the tall tarp like material. That'll be about 8 lbs each. Cut a tiny hole in one corner, and flush under bath tub faucet to remove dust. Use your hands in it to help the wash. Use immediately, but let settle a few days before introducing fish and letting chlorine to dissipate. If put in the bags, you let it drain and dry, you can store or haul it as you wish. Once bought, you likely could use this for many years.....so it's an investment. I've found some bags tear in shipping, but Amazon will compensate. When this arrives, it's about the size of 2 shoe boxes, but very heavy. Get this.

this is my first planted substrate I have only had this in my tank a few weeks and this seems to be a pretty decent, I didn't expect this was going to be red as on package it shows a dark color which is what I was expecting,its more of a gravel rock type,so if you want dark buy another product or fluorite black/dark when I first put it in even after washing it many times it made my tank very cloudy dust reddish brown color. couldn't see my fish for awhile..so this is how I used it. I've added some tips for first time users. wash it very well, there are strain holes on the sides of the bag,(which I used) I recommend using another method maybe a paint strainer bag to wash and drain it in that..secondly I removed the fish and put them into my second tank. Since I removed all of my old gravel. before adding this in my tank,lastly replanted my plants.. I used the plate method so water wouldn't mix it up anymore then it already did. After a day or so once settled down and ensuring the tanks water test was safe. I re added my fish to their original tank, I had to run two filters for a few days,I have noticed my newly planted plants have had massive new growth and I was able to cut down on the liquid fertilizers I was using them from 3x weekly and currently down to once a week after a water change.. other then the color and the cloudy messy red dust everywhere I am fairly happy with this product,I would only recommended this if you are just starting a new tank with no fish or have a secondary fish tank. it was just kinda ugly cloudy for a while, since the plants are doing well so far. Very happy with it. Most of the negative feedback seems they didn't wash it well enough or just threw it in their tank. many of the similar product reviews are the same. as long as you use it correctly it works great.

I came into this knowing it would be a lot of work, and it was, but nothing hard. Just time-consuming. I used a colander that I have dedicated to fish stuff. I did 2 loads of maybe 3-4 cups of rocks. I would close the drain and let the sink fill up while stirring the rocks. It had the added bonus of a nice exfoliation for my fingers. I had to fill up the sink 10-15 times for each "load" before the water ran clear, so it was 20-30 washes total. I think a key part is to make sure all the dust goes down the drain after each wash because it kind of gets stuck in the sink and will just add to the water each time if you don't "brush" it down. I filled the aquarium right away and there was basically no dust in the water. I am including a photo of the aquarium (not the best photo, sorry) about an hour after I cleaned the rocks and put water in. There is another photo that shows the color better. The rocks are a bit less red than they were at first because that color all washes away. There is a mixture of red, brown, tan, black, etc. It still looks pretty in my opinion.

This is my first time using Flourite, but the reviews I've read from others using it for their planted aquariums make it sound like it's the best, so I thought I'd give it a try. Read all the reviews here, as well, so it was clear that I needed to rinse the gravel more than usual. They were right. Easiest rinse turned out to be in the yard with a LARGE strainer and a garden hose on high blast. Rinsed just a little gravel at a time, but didn't take long, with the hose. Much quicker than the kitchen sink was! Rinsed until the strainer of gravel produced almost NO color when swished in a bowl of water. Put it in the tank two days ago, using the "pour the water onto a saucer" method, and was pleasantly surprised at how little color was in the water after filling the tank. Turned on the Hamburg Mattenfilter, and the water was surprisingly clear (based on the reviews here) within an hour. Planted some that day, and got a very little color in the water, which quickly cleared. Planted more yesterday. I could see a little color coming up in the spot where I planted, but nothing to even tint the tank as a whole. The pics are from this morning, but it was this clear when I moved the fish over yesterday afternoon. The betta loves it (top right corner of the front view pic), and I love it. The plecostomus will love it once there's some nice algae to take care of. FYI -- what you're seeing is one bag in a 10 gal. I'm going to add another 1/4 to maybe 1/3 -- maybe 1/2 -- bag next weekend. It needs just a little more to make some of the deeper rooted plants happy. The blue sponge in the middle is from the old tank, to help with bacteria transfer. It will be coming out of the tankafter the Hamburg Mattenfilter (the black column on the right back that also hides the pump and heater) has had time to become established. I know, I could/should have cycled the aquarium first, but with a low fish load and high plant load, and some introduced bacteria, like from the blue sponge from the old tank, I haven't had an issue with a new tank set-up in the 50 years that I've been keeping fish on and off. Frequent checking for ammonia and water changes as needed, though! If you're curious about the Hamburg-Mattenfilter, check out swisstropicals dot com. You can also make your own, but I couldn't conveniently find the right thickness of glass locally, and their sponge seems to last longer.

Dovuto lavare centinaia di volte prima di metterlo ma bello e sicuramente lo aiuta tanto in maturazione.

I’ve read countless pages to wash it or not...WASH IT. Wash it 20 times! You will rue the day you wash it any amount of times less. This WILL destroy your tank water unless you wash it

This is a neutral colour substrate, Just what u need for a planted tank, One thing I would say is you really need to wash it really well before putting into your aquarium.

Best substrate for getting plants to root in and grow. It's a substrate I've used on every planted tank (10+) setup over the years. Washing it does kind of suck as it clouds the water very quickly. I would suggest instead to put it in one of those veggie strainers and wash it before you add it into the tank.
