Best additive for plain gravel?
I have just plain old black gravel. My plants seem to be doing fine. I currently add the saechem root tabs but I keep hearing about osmocote, or root medic, or gro-soil tabs. Anyone (WHO IS NOT THE SELLER OF THESE PRODUCTS) try any or all of these out? I AM a re-planter - never really happy with the tank - but I'm getting better at just letting things be. Are any of these potentially dangerous to my fish if disturbed? which ones last longer? which are best? any input/reviews would be cool.
