Works great! By Lyadeia on 8/24/2015Lyadeia would recommend this product to a friendEver since I started using Phos-Ban and changing it once a month, I have had no troubles with phosphates in my tank at all. It works as advertised and I will continue to buy it and recommend it to others.
Great By Shane on 7/27/2015Shane would recommend this product to a friendDoes exactly what it is suppose to do
Works as Advertised By shornik on 1/28/2015shornik would recommend this product to a friendWith the exception of having to dial in the flow on my reactor to avoid the fine dust of the Phos-Ban it works just great and has already reduced my Phosphates in half.
great media By shootermcgaven on 11/15/2014shootermcgaven would recommend this product to a friendWorks better than the BRS brand. The BRS brand has more fine particles that plug up the filter mesh quicker.
the best By mrribaudo on 11/20/2013mrribaudo would recommend this product to a friendI have tried many others, This one is the best in my 150 media reactor. Tumbles without channeling.

Much more friable than I expected, but very effective By tramboneplayer5 on 5/18/2013tramboneplayer5 would recommend this product to a friendI have not used GFO before, and had set my expectations based on the videos I had seen of GFO tumbling in a reactor. I think that would turn this into powder and it would all end up in the tank. The 1/3 lb container included a fine mesh nylon bag, which is perfect for this. I dumped 1/3 of this (50 grams) into the bag and put the bag in a canister filter and in less than two days the phosphates were no longer detectable with a Salifert kit. There is almost no algae in the tank after one week. This is good stuff.
