Hi All,
At the recommendation of my LFS, I'm going to switch the substrate in my tank over from crushed coral shell to sand, in order to try and reduce the Nitrate levels which I've not been able to get under control since actually starting the tank.
Apparently, I'm aiming for at least 2inches of sand so that denitrifying bacteria starts to grow.
So, I've bought two bags of black Nature's Ocean aragonite sand in order to seed the new bed, and I've found some black volcanic sand online which is considerably cheaper than buying live sand to fill the rest of the tanks' bottom.
The sand is stated as being safe for underwater use, and the grains are 0.1-0.3mm.
So my question is, is this suitable to use? And will the fact that it's quite fine be an issue?
Any help would be much appreciated!
Best,
