GFO guru's- Can I ...

Like the thread title says,
Can i use some GFO in a media bag in a moderately moving water area of my system?

If I did, I'd use small amounts to supplement tryuing to stay low Phos.,
I wouldn't be treating any outbreaks, etc., I'd just be trying to stay in a good range, while not shocking anything like I've read about using GFO.

If you use GFO, or have used it this way, please reply.

 

It will most likely turn into a brick (clump).

It needs to stay fluidized (tumble) to prevent clumping, which is why most people use it in a reactor.

 

Id invest in a reactor. Are you still testing with API test kits for PO4?

 

Have you ever tried it? I strongly disagree, it doesn't . works okay in a bag, but is better if water is forced through it. Putting it in a bag, in a low flow hob or canister filter is good though.

 

I have used it for years in my biocube in a bag and in my 65g sump in media bag and never had it clump. Not even a little. Figure it's not as fast compared to a reactor, but that just makes it last longer, lol.

 

+1 and a little karma for M. Used Phosban for years with great result and no adverse affects on my corals.I paired it with cheato I keep in the fuge.

It is true it will clump in a filter bag so a little flow helps. Mine is in my canister to force water thru it. Just don't put to much flow or it pulverize and get into your water column which may irritate the coral. I use about half recommended amount depending on the starting Po4 readings.

 

Thanks everyone, I may try it in a fairly high flow area in a bag soon.
I currently use Phosguard that way now.

I had given/traded a lot of Chaeto away at once a while back.
NOw that my 'mass' of chaeto is really building up again, things are looking great! Even my sump has less algae on the walls.

and yes Norg- still using API for now.
Recently, DT never looked better than currently.


I'd like you to bring your Hanna tester ever, and the plugs if you still have them? ;-)

 

I have both. Im curious to see as well. Just to show you how off your API kits really are.

 

I'm home, beer is cold,
and I never said they were that accurate.
I'm mainly going by the way things look/grow.

I read a lot of current reefers experiences that low levels of both Nitrate and Phos are a little better than 0?

 

0 NO3 and PO4= dead corals.
