Brightwell Aquatics liquid products that target specific elements (such as Calcion, Magnesion, Potassion, Strontion, Iodion, Ferrion, etc.) are formulated to exceed the concentrations provided by competing products. In doing so, a hobbyist is able to adjust the composition of many more gallons of aquarium water with our products per unit volume than is possible with competing products. Because Brightwell Aquatics products are competitively priced, the result is “More bang for your buck”.
