Review: Best Seachem Products - Original Seachem product. My water had a lot of phosphates and had diatom nightmare and this product reduced a very little bit. The best thing I recommend installing a UV filter will kill floating diatom to some extent and control it by doing more water changes. The seller is a good and genuine Seachem product
