Rated 5 out of 5 by Nathan85 Great Product
Very good product for lowering Nitrates and Phosphate in a reef aquarium. I use this in my 120 gallon reef aquarium by rinsing first and then placing about 250 ml into a mesh bag and then in a high flow area of my sump. I would consider my system pretty heavily stocked, noticable signs are cyanobacteria (red looking slime), algae growth and poor growth and coloration of corals. When I tested this product I started with 20 PPM Nitrates (obviously not good for coral growth and coloration). After about a week and tesing the water a few times the system lowered to 5 PPM Nitrates. After this the tank was a lot better. Since then I wait until the media is fully saturated and the PPM starts to rise again then I replace the media with another 250 ml.
Phosgaurd is great in conjunction with regular water changes, a good protein skimmer, Chemipure, and proper feeding and stocking.

Despite the product not being iron based, I have found it to be better at keeping phosphates at 0
