What is everyone's opinion about what plant food/fertilizers are best? There seems to be the tablets (that go in the gravel bed?) and the liquid type that goes in the water. I thought I wanted tabs so that I wouldn't have to add to many chemicals to the water, but my fish store only carries liquids. Also, do I want the ones that call themselves "food" or the ones called "fertilizers"? What is the difference?
I need something that will make my new plants strong and healthy because my fish have taken a liking to eating them and I want the plants to be able to fight back.
