Undskyld: på engelsk! Fugesand eller bakkegrus?

Hello all,
sorry I write in english, but THAT is exactly my problem: I live in DK, my danish is poor, and I need help in choosing the substrate of a tank, using danish words!

I'm building up a low-end brackish aquarium (SG 1.002). I know I can save quite some money buying the substrate at Bauhaus or Silvan, but what is the difference between bakkegrus (it looks nice and dark, exactly the thing my Parambassis Ranga would love), and the simple fugesand? I would go for the first one, but I'm not sure there is anything harmful in it (organic material, chemicals, ...). What is exactly bakkegrus??

Any help?

Tusind tak!

Jeg mener der er kemikaler i fugesand

jeg tvivler stærkt på der er kemikaler i fuglesand da der ofte lander foder i det fra madskålen og de æder af det , meget af det er der endda kalk i som de æder 🙂

#3 der skrives fugesand og ikke fuglesand 😉

bakkegrus is the sand you use ind your cats liter box/tray

ups *rødmer* nej fugesand er nok ikke godt kunne godt forestille mig der er midler i til at holde alger og svamp væk

fugesand er sand som bruges mellem fliser på terresser og indkørsler, fordi det pakker mere sammen og derfor forhindre frø fra ukrudt at spire i fugesandet - der er IKKE kemikalier i fugesand....🙂

bakkegrus er sand direkte grave op, og indeholder derfor også naturligt noget ler...

Shouldn't you answer him in english ? 🙂 - It is my impression that he doesn't understand a lot of danish.

Hello all,
and many thanks. It's quite OK if you write in Danish, I can Google-translate it decently. 🙂

I read somewhere else that cat litter is actually quite OK, especially if mixed with sand. And apparently bakkegrus is pretty similar to it.

Let me know if you find out more!

Mange tak
