Calcium reactor as a phosphate reactor?

[Cory]

Would it be a good idea to use a coralife calcium reactor as a gfo phosphate reactor? Ive got a new one sitting around

I would say not for GFO..
GFO works best when fluidized.
Even if the reactor has a pump, the water volume thru the reactor likely wouldn't bring the phosphate down in your system..
But, I have never tried this method so I could be way off...

 

[Cory]

Okay thanks. That was my concern too its probably not a good idea.

 

[Reeferdood]

I don't run GFO except in an emergency.
My skimmer and bio blocks do the trick for me..

 

[Cory]

I run it as soon as my corals arent growing

 

[Reeferdood]

Hmm..
A sure sign of phosphate is algae not necessarily stunted growth on corals..
What are your other parameters?

 

[Cory]

All my parameters are great

0po4 hanna and salifert 0no3. 420 calcium, 11dkh alk, 1250mag, salinity 35-36ppt, potassium 400

It just depends how long foods in the tank

 

[Reeferdood]

How are your nitrates?

 

[Cory]

Undetectable :)

If i could remove all the algae id have a po4/no3 problem probably, as they use it up. I also dose vodka

 

[Reeferdood]

Well.. Seems to me you have a ULNS which is likely what is stunting or killing your corals..
I would try to bring your traits up to 5-20 ppm..
You might be surprised at the results..:D
