Super Fine Sand
Very fine white sand and very easy to clean. Only needed to rinse once or twice to get clean, unlike other sand I've used, when I needed to use more water than an Olympic sized pool holds, to clean.My Mbuna love it which is the important thing. Good value for money. Great sand go ahead and buy it, you won't be disappointed 😃👍

Looks absolutely great in the aquarium
This is a very fine sand as long as you’re aware of that it is fantastic really stands out in the aquarium Corys love it always burying their noses in the sand. I have an 85 L tank and used approximately 1 1/2 bags of this to give enough for planting the plants. Love it too rooting really well I’m having to trim them weekly to prevent them overgrowing the tank.

Pleasing colour, harder to set up than “gravel substrate”
My second fish tank set up. This was for prawns and loaches. Obeyed the instructions and washed it thoroughly ( about 8 times), could not get it to clear, put it in the tank, filled with water, very cloudy. Eventually my carbon filtered pump cleared the water with the addition of a water treatment, now it looks fine.

Very nice smooth sand
I really like this sand and bought it for a new set up I am starting. It is not cheap, but it will last years. I got 20kgs or the light River for my 155 L cube, which was just about enough. I washed one bag at a time in a bucket, draining and rinsing about 6 times then added it to the tank. There was some clouding left, but it only lasted a day or so. The pictures above are when I added it and about 14 hours later. The grains are not too fine, and seem to have no sharp edges which your bottom dwellers will like. Obviously there are no nutrients for plants, but you can solve that with root tabs for the plants that need it, or just place it over a sub soil. I use a large diameter siphon vac. And the sand can be pulled into the tube, but it is easy to drop it back out, or, even if it reaches the bucket you can just add it back in.

Hard to rinse but worth it!
The media could not be loaded. So I had a problem with my tank that was causing my fish to die...so i took the decision to completely empty my tank. I opted for the sand gravel as i read its great for shrimp and bottom feeders. The sand gravel is really hard to clean. It took me 36 buckets to rinse it. My tank was a milky colour for 10 days, but it was a complete tank change, so it was to be expected. As hard as it is to rinse, I would do it all over again as it looks great! The food sits on the top too, so i can see the tank keeping clean for longer. I have a 110 litre tank and 10kg gave me about 2inches on the bottom.
