Necessary for root feeders and low tech tanks
Reviewed in India on 21 May 2020
Great product for low tech planted tank . I use it in white sand for my root feeders like swords, crypts and vallisneria. Good growth. Reducing one star since it's way expensive, in fact all Seachem products are. I have grown plants even in gravel using this. There are diy cheaper alternatives but if you have expensive fish its not worth the risk. This is completely safe for the fishes.
