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

Comfortable and light!
Color: Brown, Size: Large
Wanted something that was going to be lightweight but had those longer sleeves because I do still get a tad chilly even on the warmer days. This is perfect, the fabric is lightweight and breathable, the loose cut around the waist adds to the top's "breathability," but it still keeps you cozy and warm on those chilly mornings! The brown is a lovely warm-coffee tone and it hasn't faded a bit in the wash. Very nice shirt to add to your collection!

looks nice, well made and styish.
This was a gift for a friend.
It is well made, has a good modern style to it, comfortable to wear, she is taller, and it fits her well. Its a bit warm, so a fall kind of clothing option.

Great for layering or wearing on its own!
I’m 5’6” and ordered the small — it fits perfectly! The color is exactly as shown in the pictures, a beautiful beige that goes with everything. The fabric is incredibly soft and comfortable, making it great for layering or wearing on its own. I’m really happy with this purchase and would definitely recommend it!

Nice but not great
Fits true to size. I ordered a small and it was a great fit. Could be a bit softer. Loved the style. Not too thin or not heavy, nice weight. This quality of the sweater was nice, however the buttons broke apart as I was styling the cardigan. Not happy to have to sew on small buttons to fit the small holes. It’s nice but I had to put too much effort into wearing it.
