I'm assuming by my lack of green dlime and hair algae it has worked as promised. Thanks
It really does mean granular By James on 5/13/2015

I've only had the GFO in for about a week now but I've been testing every day (too much time on my hands) and my phosphate level is definitely on its way down. Not enough time yet to say anything about the algae, but science doesn't lie. I only have one thing, filter socks don't work with this. I put it in and started to rinse it out and it started coming out of the sock like dust (which it is). But that's my lack of experience, not the product.
A must for reef By Deafclown on 5/6/2015

I wish I had used this in the beginning! I believe it's a must have for a reef to help keep phosphate down and calm the algae growth.

This stuff rocks! Keeps my phosphates at 0. I change it once a month, though I am sure it would last longer if I left it. Never hardens or clogs. Love it!!
PRICE AND QUALITY By machote on 3/27/2015

very good product i used to run a ATS (alggae turf scrubber) it was great but so much evaporation and maintenance needed each 7 days, also you need to design it very well and do a lot of research ( i spend a lot of hours? a lot of $ on light because u need a watt for gal now imagine in a 300 gal reef tank, also water splash etc, this gfo does the same but less work so then this is GREAT no maintance needed just replenish each month or month and a half

I was watching Mr Saltwater Tank on u-tube ,he turned me on to bulk reef supply. I was having a big algae problem . He said to use BRS bulk Gfo in a reactor .The algae was out of the tank in 3 day /with light out . Wow this is the best my 15 year old tank has ever looker. Also it was a great price and was shipper very fast. Will buy all my need from BRS

This works very well and I have only been using my gfo from brs. Very straight forward I run mine in a canister along with brs carbon in another canister I simply fill, install open my ball valve and rinse with tank water until dust particles at minimal or just until water comes out clear so it helps with a 1-2 gallon water change in my total 90g reef. Also I only have to change it every month and a half to two months on my bio load very good. Thanks BRS!
