- RowaPhos Phosphate Remover
- Significant adsorption ability - 25 g of phosphate per kg of media
- Once exhausted, will not leak back into the water
- Easy to use and will improve the water quality by removing Phosphate
RowaPhos was developed in Germany for treating main water supplies. RowaPhos is a patented, man made ferric hydroxide material chemically engineered for the efficient removal of phosphates, arsenic and silicates from fresh and saltwater.
- 100 g/100 mL RowaPhos will remove 3ppm of phosphate from 100 US gallons of saltwater.
- 250 g/250 mL RowaPhos will remove 3ppm of phosphate from 250 US gallons of saltwater.
- 500 g/500 mL RowaPhos will remove 3 ppm of phosphate from 500 US gallons of saltwater.
- 1000g/ 1 L RowaPhos will remove 3 ppm of phosphate from 1000 US gallons of saltwater.
- 5 kg/5 L RowaPhos will remove 3 ppm of phosphate from 4500 US gallons of saltwater.
RowaPhos Recommendation for Use:
- Never wash the product unless fluidising.
- It must be kept damp at all times, it is not as effective if it dries out therefore, replace the lid if not using all of the container.
- Place the product between two layers of filter wool in a canister filter.
- Do not sprinkle into the your reef tank.
- Do not place it into water without surrounding it with filter wool
- RowaPhos recommends that you use a small quantity and replace regularly rather than a large amount and replace infrequently.
The Best By BouncingSoul on 9/17/2017BouncingSoul would recommend this product to a friendDon'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.
Does what it states. By ajoe on 3/2/2017ajoe would recommend this product to a friendGreat 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.
5 Stars By reefer on 9/6/2016reefer would recommend this product to a friendyup.. 5 stars!
Works quick By Ricardo on 8/13/2016Ricardo wouldn't recommend this product to a friendIt work great and fast even before using a reactor it work great even on a bag in a high flow sump area
Great product By Edward on 6/24/2015Edward would recommend this product to a friendThis 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
Awesome results By Tim on 2/21/2015Tim would recommend this product to a friendRunning 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.
From .20 to .02 By adam on 11/6/2014adam would recommend this product to a friendgreat stuff brought my phosphates down within 3 weeks of use.
Does what it's suppose to do! By Stephane on 6/6/2014Stephane would recommend this product to a friendSince 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 4/21/2014Trevor would recommend this product to a friendDeciding 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.
fantastic By Jimsreeftank on 2/11/2014Jimsreeftank would recommend this product to a friendi went from phos of .5 to .2 in 18 hrs!!
good product works great ... By Ocean11 on 2/8/2014Ocean11 would recommend this product to a friendI just started using this product for a couple of weeks now and have brought my Phosphate readings dow from...0.50 to 0.07 good stuff
good product By VAL on 2/7/2014VAL would recommend this product to a friendmy phosphate levels were .50, i have now got it down to .07 in only a couple of weeks great product, in one of the reviiews above it says to rinse it ...you are not suppose to rinse it according to the instructions...

Keep using it and let it go as low as it can. Phosphates usually aren't limiting to micro algae until they get below .03, so that is generally the target number but even lower is better as phosphates have other negative side effects such as slowing coral skeleton growth, though in most cases the phosphate itself isn't toxic so much as it has a lot of undesirable side effects (like being algae food).
It can be mixed with your choice of carbon in a media reactor. More than likely the carbon will become exhausted before the Rowaphos does, and you may not want to use a whole dose of Rowaphos since you may need to change it more often.
It comes in a small plastic container. Its best run in a fluidized bed reactor or at the very least you would want to put it in a filter sock.
This will use around 300 mL of Rowaphos. Feel free to let us know if you have any further questions!
This can work with standard media bags 500 micron and even higher without issue. It can work and not escape in a felt bag perfectly. Ideally GFO should tumble for best performance. Feel free to let us know if you have any further questions!
