Theres a bonsai shop in SF that sell the exact same rocks in the pictures you posted. it was only 1.50/pound. ironically, this bonsai shop is less than a block away from aquaforest aquarium here in SF and the seiryu rocks look identical to these. but they go for 3.99/pound. These rocks will dramatically raise pH and KH in small tanks (less than 20 gal) so becareful if you are keeping fish or shrimp that need soft acidic water.
