In an independent series of tests carried out by the Berlin Technical University on the five most commonly used phosphate removers at the time, RowaPhos was found to be the most efficient in removing phosphate from water. Other medias tested reached only to 30 40 % of its removal capacity by weight. Additionally RowaPhos was found to continue to remove phosphates at lower concentrations and had a higher maximum holding capacity.

Is it a coincidence that a German company favored a German developed product? I read the same info on the web site.


Thanks for your input. I'm leaning to rows but hoping to see what the masses say. It's pricey.

it's very messy too.

I prefer the BRS HC and have used all the GFO in your poll.

It's got very few fines and most likely wasn't one of the 5 GFO tested in that study.

I prefer the HC GFO from BRS as well, but you use such a small amount, especially on smallish tanks, that you really have to choke the flow back in the reactor to prevent it from tumbling. On the other hand, I do like the RowaPhos, but it is sooo pricey...

I thought all the good stuff come from Germany anyway. Lol

I don't use gfo but when I did I liked the product

PO4X4... is can be regenerated, works well in reactors and has a high capacity. Not sure I believe the X4 than GFO, but definitely good.

i get my gfo and gfo hc from Elias. I've used others but I found the price and success to be best with his gfo

Waitaminute.. I don't want to be tumbling? Did I confuse gfo with bio pellets? Arghh

His site is down and therefore not convent for shopping with him. No browsing possible.
