Experienced SPS keepers, are you using GFO's?

[Greg Hiller]

Are you using Granular Ferric Oxide (GFO) phosphate removers?

 

[SunnyX]

Rowaphos here. Never seen a difference either way but I still run it.

 

[REEF-DADDY]

I use the generic stuff from Dr foster and Smith. I wonder sometimes if my po4 is too low and out of balance with my No3

 

[alde]

I use Phosban with good results. It allows me to feed more without the problems associated with too much PO4.

 

[gcarroll]

I am using Warner Marine PhosAR. It is the best I have uses so far. It is the first GFO that has got my phos down to 0.00 on the Hanna colorimeter. The best I ever did with Rowaphos or Phosban was 0.03

 

[Gary Majchrzak]

Occasionally I will use a GFO PO4 remover. (Not an option in the poll.)

 

[fishdoc11]

I tried Phosban soon after it came out. I had some coral deaths like lots of other people at the time.......possibly from using too much and not rinsing well. I haven't used any since and don't really see a need with good skimming and maintenance practices.
FWIW, Chris

i use rowa along with good skimming and frequent water changes

allows me to keep my corals from starving.

 

[ReeferAl]

I bought a bucket of the stuff at about 1/4 the cost that should last me a couple of years. I was warned though by the person referring me to the site: "don't tell them that it's for an aquarium. If you do they'll tell you they can't sell it to you". Basically, they have an exclusive arrangement with someone who repackages it for aquarium use.
Of course, we are on well water and I only use it to remove arsenic from the well water, never for the aquarium.

Link, please?

 

[SuperNerd]

:lmao: Yes, link please.

 

[DaddyJax]

I dont use it. I dont see any reason other than temporary removal.

 

[Kip]

... why you'd use it continuously.

any tank is constantly importing po4. there are a variety of ways to deal with it with the bioload dictating what is best per system. For my system, fluidizing rowa is the most direct way to export po4.

 

[REEF-DADDY]

Kip I am with you on this one. My tank is very heavily stocked, I fed heavily, and have a keen focus on nutrient export. For me running a GFO is like good insurance. I don’t need it, but its nice to know its there. I wonder how many of use would use such a product for No3 if one exsisted……….

I need some to get arsenic out of my well water also. Do you have the link?

He was refering to ocassionaly instead of constantly

 

[twon8]

never had a need for it, my po4 and nitrates are low, only algae is on the glass.

 

[DaddyJax]

I personally think that it srtips more than P04 out of the water.
