High capacity gfo

randy4083 · Mar 13, 2016

Can you run chemipure blue and a high capacity gfo in a reactor at the same time or which one would work better

GROSSR · Mar 13, 2016

Yes. But I wouldn't.

First HC GFO can be regenerated. Once combined you won't be able to separate. I am not aware of Chemipure being regenerated.
Second, I would want a different flow rate for GFO than chemipure.
Third, GFO could be exhausted in a few days, and your Chemipure should last a lot longer.

BRS sells a dual rector for Carbon and GFO, for specifically this reason.

I got chemipure blue in a bag in the in a hang on the back filter and I was gonna run the gfo in a reactor

I worded my first statement wrong I just noticed that I'm a little tired right now

It is fine to use them at the same time since they do entirely different things in seawater but in a reactor the GFO should be moving and with a packet of Chemipure in there too it may be hard to accomplish.

So I can run a bag of chemipure in my hang on the back filter and run gfo in the brs reactor

Yes, that is fine.

Bear in mind the Chemipure ion exchange part is not very useful in seawater, except perhaps to bind some organic matter. So it is really just a way to use activated carbon.

So I minds well just run the gfo after the chemipure runs out so what would be good to use with the gfo if anything

Randy Holmes-Farley · Mar 13, 2016

Use with the GFO for what purpose?

I use both GFO and GAC on my system.

How dirty is your water?

randy4083 · Mar 14, 2016

I do a water change every week with rodi and the water is clean but I've been having algae problems so I got the high capacity gfo because where I get my water from said that it would take care of the algae

It might. One way to reduce algae problems is to reduce phosphate available to it, and GFO is one way to reduce phosphate.

Ok thanks and I'll test my parameters later and I'll let you know what they are

GFO can be exhausted extremely quickly, as in a few days. You need to find the source of the phosphates. In my case it was my rock. My GFO was exhausted after 2 or 3 days. I removed all the rock and treated them in a tub with Lanthanum Chloride. I added a Biopellet tumbler a few months ago and my GFO is lasting longer, as in a few weeks. I also regenerate my GFO with lye.
