Product Review: Phosguard

Phosphates can cause many problems to marine aquariums by harming corals and allowing for algae outbreaks. Phosphates can be added to the tank through fish food, water changes, and fish waste. Algae love it and will grow like wild once their is enough in their tank. The best thing you can do to prevent algae outbreaks is starve it of nitrate and phosphate. I bought Phosguard from my LFS and have been very satisfied with it. My phosphates dropped to 0 in under 3 weeks. I have also had no algae problems whatsoever.
To use phosguard, it's first a good idea to do a few other things. First make sure your nitrates are in check and then get your phosphates tested if you still have a problem with algae. Your levels should be 0 ppm but 0.3 ppm is ok. The best way I have found to remove phosphates is to install phosguard in your filter. It usually comes in a bag with little white balls and you just throw it anywhere that there is water flow. You can find it at your LFS but it is definitely cheaper on amazon. If you are treating an older tank that has an algae problem, change this bag every 3 weeks and then once your phosphates are under control, change it every 3 months for prevention. The Phosguard first pulls the phosphate out of the water column and then will pull it out of your live rock and sand which might take a longer time especially if your tank is very established. If you just set up a new tank, this is a great product to prevent any and all algae problems in your aquarium. It is much better to do this prevention rather than buying many more things later on to get rid of your algae.
