I am about 2 hours from putting sand in my new tank 15 G with 24w T5 light I am going to use it to try breeding livebearers I want to have some nice plants in there with a sand base but nothing to hard to grow do I put a layer of laterite down then sand on top or will it be okay or better to use ferts either tablet or liquid form. Also if I use laterite can i mix the sand with it or does it need to be done in layers? The sand is just really cheap argos play sand.
Thanks
