Don't rinse it! The liquid that is produced when you first use it will help with phosphate and silicate. I've used just about every GFO product out there and nothing compares to Rowa.

Great product and works very well. Was running another product and have had much better results with this. I allow about 1/2 gallon of runnoff with media change to strain out the issual residue.

This thing is amazing, I was running a different product before and it took a while to get the same results with this one in just one day, amazing just make sure to rinse before using it

Running in reactor. Started with .25 level and within one month results are .01. Was running rowaphos at a slight tumble, wasn't getting results so I opened ball valve up a little so I didn't have any dead spots in media and bam....phosphate levels dropped to .01.

Does what it's suppose to do! By Stephane on 6/6/2014

Since i have a new tank and it's settling in, i was faced with a rapid green hair algea bloom. all the while i still had diatoms galore after 8 months. I bought some live stock to help but was losing the battle. As i did more research i found out that my cause was high phosphate. sure enough my levels were high. So i purchased a reactor and put BRS Bulk GFO Granular Ferric Oxide. I lowered the phosphates successfully to 0.02 and holding. The green hair algea is slowly dying off however my diatoms are blooming.
I switched to this products are diatoms are indication that there is a high level of silicates. I've been using it for about 1 week now, and i have noticed a drastic reduction of silicates and my phosphates are at 0.01!
Hopefully, a couple more weeks and ill be rid of the algea
A good decision By Trevor on 4/21/2014

Deciding to run phosphate remover was one of the best decisions I made when setting up a reef tank. Rowaphos works well and lasts for a couple of months before it needs to be replaced.
I know the product says not to rinse it, but I would never run this without rinsing it. The best way to change media is to combine it with a water change.
-Remove old media and drain reactor
-Add new media
-Route the reactor effluent to a 5 gallon bucket
-Turn on pump and run 5 gallons through it
-Put 5 gallons of fresh saltwater back in your tank
-Move reactor effluent back to sump and dump the red waste water
If you don't rinse the media, you'll blow red particles all around the tank. Soft corals seem especially sensitive to it and will shrink up for a day.
