API First Layer Pure Laterite Aquarium Planting Medium, 55-Ounce

Bought some on Amazon, it was over $20 at all the nearby pet supplies stores. I mixed this into the lower gravel layer in my 20 gallon plant tank, containing mostly frill, cabomba, and java fern, and they are all doing extremely well. I don't use any other supplements in my tank, everything is 100% healthy!

This substrate is good for plants in long term. but make sure to wash it 2 times before adding into tank. it make my tank cloudy even though i use the best canister filter. Place a thick gravel on it (at least 1.5 inches).

Got this for my 5 gal tank. I placed about an inch of gravel on the bottom, layered the entire box over the gravel and topped it off with another inch of gravel. I placed my several plants prob about a dozen or so into the gravel and substrate. I read on one of the aquarium forums that you can use Jobe plant spikes (Only Jobe by the way, something about the chems the use in it). So I placed the plant spikes into the substrate under the plants.

WOW...WOW

After about a week everything was exploding. The plants were growing like crazy. I had to trim them after the first month. So yes this stuff works great but it is only a substrate..you still need to provide nutrients to the plants
