Last time i set up a tank i used First Layer Laterite followed by my sand. I am about to re-work the tank with a new fine black gravel/sand instead, and was considering what to put underneath. I asked a question about whether to use root tabs or something like laterite, but only got one reply. I am now thinking of going the same route as I did before, but I am just checking if laterite is still a good option or whether there are any other good alternatives (black would be great).
I already have the sand, so I am trying to avoid suggestions which are the fert and the substrate in one..
Many thanks
