Most plants need iron in fairly high levels for proper growth. Laterite is
very high in iron, it's basicly rust, and really helps rooted plants. Some
gravels, like fluorite can be used instead. I also recommend a trace element
fertilzer high in iron to be added a couple times a week. Iron will
precipate out of the water and become difficult for plants to use, so
regular dosing with chelated iron helps alot.

What are your views on it's use? Does it help? Is it worth the money?

I am a plant newbie and just added CO2.

Thanks,
