Review on Reef Fusion - 2.4 Liters / 1 Fluid Gallon by Maria Sandoval

Works great, I use this for my reef tank. Also, do yourself a favor and buy a bigger bottle to save money even if you have a small tank. I currently have 4 seawater units and this size suits me best. But I can only imagine how much money I wasted buying 500ml and 1 liter bottles. Pro Tip: Save your 500ml or 1 liter bottle and fill it with a large bottle for easier access, less spillage and easier hydration, then you can store your larger bottles.
