Grain size: 1-1,5mm. -stabilises pH and hardens the water -perfect for rock biotopes: Tanganyika, Malwai, Lake Victoria -giving an alkaline reaction. The fish that inhabit these lakes do not live in the ooze (up to 0.5mm) but in the sand 0.5< 2mm which also allows the gills to be cleaned.

100% NATURAL. Every owner of underwater pets knows that decorations and aquarium substrates not only look nice, but also affect the environment of our fish. That is why it should be ensured that most of them are natural. Not artificially coloured and looks natural.
Some of the used sands have very little influence on the chemical values of water. It is therefore advisable to use such materials for the substrate of Tanganyika aquarium which would have a high content of magnesium reacting with our water. Such rocks include DOLOMITES.Metasomatic dolomites were formed in the process of metasomatic transformation of limestone (calcite) deposits. In this process, the calcium carbonate they contained was partially displaced by magnesium carbonate. The source of magnesium in these transformations was sea water.
Before use, we recommend that you only pre-wash the substrate, please do not do this thoroughly because it is a never-ending work. After pouring out the substrate into the aquarium and covering it with water, a natural cloudiness may occur, which will disappear very quickly after starting the filtration.
Please note that the total weigh of a bags may vary +/- 2%
In order to create a 4-5 cm thick layer of substrate in an aquarium of a given bottom length the following is needed:
30cm / 1ft = 5-7kg
60cm / 2ft = 10-15kg
80cm / 2.6ft = 15-20kg
100cm / 3.3ft = 25-30kg
120cm / 4ft = 30-35kg
150cm / 5ft = 50-60kg
200cm / 7ft = 80-90kg

Not bad. Not great.
Size: 5 Panels, Color: Grey
This was very heavy. It wasn't too hard to assemble but you do need two people. Sadly did not help with the noise I was hoping it would. For the money I spent I was hoping for more.

It has no sound insulation function at all
Size: 5 Panels, Color: Grey
I purchased this soundproof partition with the expectation of creating an independent and quiet office environment. However, the product does not deliver effective sound insulation. The ambient conversation noise outside the partition measures 50 decibels, and the noise level inside remains unchanged at 50 decibels. Given this lack of performance, I would like to inquire about the actual acoustic value of this partition. This constitutes a clear case of misleading advertising.

Partition Divider
Size: 5 Panels, Color: Grey
The Natwind 5-panel portable partition is ideal for creating privacy and dividing office space. At 122.8" x 71", it provides substantial amount of coverage, and the folding design makes it easy to set up, move, or store as needed. The freestanding structure is stable. The acoustic panels are quite thick at about 1/2in thick and help reduce noise. Its neutral color and design blends well with most office interiors. Overall, this partition is a convenient and effective choice for temporary or flexible workspace layouts.

Great quality, easy to set up.
Size: 3 Panels, Color: Grey, Size: 3 Panels, Color: Grey
I actually have this in my bedroom, replaced a non acoustic panel with it. These make a huge difference. As someone who is always playing music on their speakers I don't want to bother my roommates too much. Easily can hear the difference once these were in place. The panel itself is high quality and thick, what's a really nice detail is how they are attached together, there are multiple wedges just like foam noise dampeners which is super cool! This thing is easy to move around and can be folded for storage with ease. You get extra screws just in case you lose any, the feet are made out of metal which adds to the quality. There was a very slight chemical smell when taking it out the box, however that went away in just a few hours.
I can imagine using this in a noisy office, surrounding yourself with these in a cube shape will make all the difference to focus on your work. These panels are great and if you're looking for quality, I'd say you can pick these up without worry. No issues on my end!

Office Divider
Size: 5 Panels, Color: Grey
This office divider is well made and easy to assemble. All you have to do is install the feet. The panels are only about an inch thick, but they work surprisingly well at muffling unwanted background noise.
