Query: Great product

I have problems in my aquariums with silicates in the tap water and therefore brown algae - this product takes care of that issue and keeps my plants clean and green. I keep bettas, angels, cories, barbs,neons and mystery snails/trapdoor snails and none are in any way affected by the product.I'm a big fan of the Seachem line for aquarium maintenance, water treatment and plant fertilizers.
