Which aquarium plants need root tabs?
Cryptocoryne plants (or crypts), sword plants, bulb plants, carpeting plants, and plants that produce runners all tend to feed from the substrate and will greatly benefit from root tabs. Stem plants like bacopa and moneywort can absorb fertilizer from the water or ground, but they seem to prefer the former. Plants that don’t need substrate to grow – such as mosses, floating plants, anubias, and java fern – typically do not use root tabs as much.
