I currenly have plain black aquarium gravel as a substrate. In my tank I am growing anacharis and am looking to get dwarf hairgrass. I am using diy co2 and no fertilizers. I have seen flourite aquarium gravel and have been told it is very good. My question is do you think its worth replacing or adding to my plain gravel with this fertilizer substrate or is it just a waste of time and money? If you think it's a good idea, in what way will it change my water quality. My ph is already low and I really don't want it to drop. That wont be very good for the fish currently in the tank.
Thanks in advance.
