im looking into a new all in one fertilizer. currently im using dustins fish tanks growth juice, but it has a huge clump of white fuzz thats growing the size of a tennis ball inside of it. that cant be good. on amazon im reading reviews about thrive c of people saying if they follow the directions it has killed lots of fish. are there any users of this product here with fish and some recommendations on dosing. it seems like it grows awesome plants but i dont want that at the cost of the fish. any other good all in one ferts?
