PM started 12 hours after adding PO4 remover

[E-A-G-L-E-S]

I had this happen to me the last time i used Phosban and now with PURA Phoslock.
I feed heavily, which i have cut back on for the past month or so 'a little' because of obvious elevated levels of PO4.
My 58g with the exception of my 6" crocea and a frogspawn is all sps and they are all doing exceptionally well...great growth, great deep colors and good PE.
I also have kept a strict water change schedule since day one over two years ago of 7%-10% weekly.(Reef Crystals for this tank)
I get a green film algae on glass everyday that i mag-float off.

I believe, however wrong i am that these elevated levels of PO4 contribute to my great coloration....impossible?

How can I, or do I, want to reduce PO4? Should i leave it as is?
I have read that elevated PO4 levels will absolutely stunt growth in sps but mine 'seem' to be growing quite well.

Thanks for any help!

edit: I already removed the Phoslock

if your livestock is doing fine without the po4 remover, isn't it a no-brainer?

i have heard of issues with phosphate removers and pm, however i have NO IDEA how the two are related. if pm is caused by an external protozoan, how is this related to phosphate removal media?

for your po4 issues, there are a few things you can do:
better skimmer
phosban reactor

Phosban reactor with carbon you mean? Already do that.
I don't believe my skimmer is in need of an upgrade...what do you think?

~ 70g total system....using a Bermuda Aquatics C5 on a Ocean Runner non-needlewheel.

I pull about 3/4 a cup a day(about 15-20oz.) of drak tea with more solid waste usually stuck in riser inside of cup, which i clean 'daily'.

phosban reactor with Warner Marine HC has incredible phosphate absorption.

How many gallons is your skimmer rated for?

And are you in PHilly?

 

[E-A-G-L-E-S]

Still a PO4 remover

200g


north of Philly in Allentown

i would say the warner marine HC is a whole different level from your regular phosphate gfo media. ask gcarrol for beta testing results.
i used to live downtown by rittenhouse square

 

[E-A-G-L-E-S]

My lfs just started carrying the warner brand but no HC yet....is it out already?
Nice, my cousin lives in RS and most of my family is in NE Philly

 

[ezcompany]

the first version is good for low flow set ups. the HC is great for phosphate reactors. both are excellent in phosphate absorption and do not leak any crap into your system

 

[jbittner]

it is my understanding that the protozoan feeds of the Iron that the PO4 remover leaches back into the tank. Atleast that was the thought when I was battleing PM.

 

[E-A-G-L-E-S]

I thought i've read that before as well.....so does Warner leach iron as well?

 

[jbittner]

All selective ion media has to leach something.

 

[E-A-G-L-E-S]

So what can i do about PO4 then? if only so i have less of a task keeping all four panes clean.

 

[jmaneyapanda]

no one even knows what protozoan causes PM, so I dont know how that can say what it feeds off of.

 

[ezcompany]

yup, its still a big mystery.

 

[jbittner]

I will take anything that Barry say as the truth. He believes it is caused by a protozoan (a least last time I talked to him).

 

[E-A-G-L-E-S]

So do i need to think about removing my clam?

Abstract

Two types of iron chelators, desferrioxamine (DFO) and 2,2'-bipyridyl (BIP), selected for their differential binding properties, permeability and stoechiometry, were tested for their ability to inhibit the in vitro proliferation of the carpet shell clam parasite Perkinsus atlanticus. A tetrazolium-based assay was used to determine the effect of the drugs on cell proliferation. Both chelators were able to inhibit P. atlanticus proliferation in a dose-dependent manner, the 50% inhibitory concentration were 14 and 24 mM for DFO and BIP, respectively, in a 72 h test. This effect was reversed by co-addition of iron, confirming that this activity is due to the sequestration of iron. These results indicate a high degree of susceptibility of the protozoan parasite to chelator-induced iron deprivation. However, this effect was reversible upon removal of the drugs, indicating that the action of both chelators was cytostatic. For the range of concentrations tested the combined drug effects was not significantly higher than the additive effect of the individual drugs.

uhhh.....so does that mean when i added the media it started to affect and then upon removing it quickly and doing a water change i removed the threat? If that sounds dumb, it's because that reference totally goes way over my head, sorry.

you need to somehow remove th iron. large amounts of carbon, water changes whatever. you may need to give the clam a FWD also

Yeah, but there's like a gazillion protozoans in the world. Each has their own requirements. Protozoans are just a classification of a life form.

Mbbuna- interesting article. Of course, if we only knew we were dealing with Perkinsus sp. as the cause of PM.
