Could you give me any suggestions, as far as brands/products? And what if I don't want to disrupt the substrate? I think I've heard others just make up a bottle of their' own fertilizer dosing by mixing water with their' dried stuff... lol
Many folks here including myself order from here:
As far as disrupting the substrate, are you referring to inserting fertilizer into it? If yes, you don't need to do that with AS in the vast amount of setups. Just dose the water column.
