Review on 🐠 PhosGuard Aquarium Media, 2 Liters / 67.6 Fluid Ounces by Melissa Kula

My pick for the best phosphate remover for the money. On reef systems with up to 75 gallons of salt water, this along with weekly water changes will help keep the aquarium balanced. Along with avoiding overfeeding the aquarium, this helps prevent cyanobacteria, which I refer to as "psychobacteria" or red algae. Cyanobacteria are so frustrating that many people are giving up their saltwater tanks. I've been there about 6 times myself. I typically change PhosGuard every 6-8 weeks or more often if my tank's phosphate levels are getting high when testing the water. After adding the recommended dose for your aquarium size to the middle bag, you should rinse it well with reverse osmosis water. Otherwise, you will end up in the aquarium with a huge amount of dust. Even after rinsing, you will notice the dust release when you put it in the aquarium.
