PO4x4 = iron based polymer?

[xtlosx]

Hate to resurrect this, but any longer term updates? Looking to try some over the regular BRS high capacity GFO.

The OP is apparently banned from RC, so there may not be any updates from him or her.

Well I have used them for quite a while. The cost and mess to regenerate for me was not worth the mess. Also noted my chaeto started to shrink in my fuge. Not from less PO4 but probably from lack of Fe, my tank ran around .4 to .8 on Red Sea or Hanna colorimeter. Same as on GFO. I have switched back to high capacity GFO as it is more cost effective and less trouble for me. I experienced my reactor clogging and needing more frequent service. Could be due to tiny size of beads. Now back on GFO my chaeto requires frequent harvesting.

FWIW, if the concerns are fine particulates and a need for excessive gfo rinsing , BRS HC gfo which is quite dense, 1.75 times as dense as granulalted gfo, gives little dust with minimal einsing and holds up well in a reactor. It also stands up to the regeneration process well.

Interesting. I've been using high capacity GFO for a while, and figured I would try something new as I still am battling a phosphate issue even through all of this. We'll see how it goes, just ordered a bag.

Please keep us updated about the progress. I've been using Rowaphos and have contemplated switching.

So have been using about a little under a cup since Monday, phosphates were .08, then the next day, not even 24 hrs and was down to .05. Doing great, glass is still spotless. PE on my SPS was overnight twice as big... so they are obviously feeling good.

My tank is laden with phosphates and have been battling an issue for a long time, but so far so good. I think the "wave" action of the polymer vs tumbling of the pellet GFO is where I'm getting the best results from. Half of my old GFO would always clump up at some point and be rendered useless, but with this, it just waves and is all basically suspending and constantly moving.

So far, so good!

Thanks for the update. How long will that cup last before you have to replace it?

Well, just tested this morning.. .00 and at this rate, I won't be changing it for quite a while actually. Next time I add it, I'll cut it in half (either half cup or even potentially less).

This stuff is absolutely amazing.

sorry to stir up an old thread again, but anyone have more long term info on this product? I am very limited in choice of GFO since I am in Thailand.

Actually I only have 2 choices, keep rinsing Rowaphos or use this instead.

any info would be appreciated, thanks!

So I have been using this product continuously, and LOVE it... Last couple months, they had some production problems and wasn't available. I had to use Rowa, and or BRS stuff and noticed a large difference. I'm back on PO4x4, and I love it.. so glad it's back.

how long does it last?? and how much of this stuff do you use?

 

[bertoni]

Well, it's basically GFO, so I'd expect a fairy similar amounts whichever you're using, although the polymer coating might reduce adsorption. It should last about as long as GFO, as well.
