Thank you for your interest in this Tetra product! Yes, it can actually be used for that purpose as well. However, it will turn your water very dark for several days, due to the peat in the product. Since it is designed for ponds, this helps reduce the effect of sunlight on the water. You may not like the effect so much in an aquarium, however, as it will make your tank look similar to the Amazon with all of its tannins.
