They are fertilizers. From what I am reading online, Florapride are pretty bad fertilizers. I've read multiple reviews that it doesn't do anything for the plants and it is lacking nutrients needed. I mean you could give it a try weekly... see what it does.
I made the mistake of buying a fertilizer that the fish store recommended to me... turned out it was a bad fertilizer to use and was killing my plants by overdose of some nutrients and not even adding other nutrients. Thanks to Bryon, he suggested I use one of those two and it did wonders for me. My plants made a complete turn around and are doing fantastic now.
