needing help with Phos!

[ashr]

Hey all

So I have been battling high Phos the last few months and cannot for the life of me get it down...

Right now it is sitting at .22 (Hanna Checker)( API looks like .01-.25)

I try and do a water change of 5-10 gallons every 2 weeks or so. I run RowaPhos and Chemi-pure Elite.

Calc - 500 ( doser was running a bit high)
Mg 1350
Alk - 10



Anyone have any idea how to bring this sucker down? Thanks

Phosphates are difficult to bring down without GFO. I battled phosphates for months, and I didn't really make a dent in them until I started running ROWAphos in a reactor.

I've heard good things about clearFXpro.

At this time I am running ROWAphos in a TLF 150 reactor and have Chemi-pure elite in my tank as well. They don't seem to be doing it..

I also picked up some Seachem Phosguard but have not tried it yet..

DO you have lots of flow??, Maybe try power heading your rocks to get any detritus out and into your water stream, then do a large water change, then change your GFO shortly after

If you want to get a deep nutrient sink P04 laden tank down quickly, use Foz Down. Then use GFO for normal ongoing maintenance.

This could work too. I am going to do a large water change today :)

Thanks for the tip

It's one thing to treat the symptoms, another thing to fix the cause.
Knowing more about your set up would help, and a picture would be best.

I wouldn't use the Phosgaurd with SPS

I agree no point in trying to band aid fix a phosphate problem until you know the cause. I had high levels in my 90g and was advised to get rid of some of my sand bed depth as I had 2-3", so I removed a 5g pail and a half of real dirty sand bed and am now at 1" max. The detris build up was causing some of my problems, as well I added another wp25 wavemaker power head to increase the flow in and around the live rock which helps to blow any build up off them.
I have about 100 gallons of water volume between the DT and the sump after taking into account rock displacement. and do 25% RO water changes every 2 weeks. I also run GFO which I plan on changing every 4 weeks, until my level is at an acceptable reading, once it's there I'll check the PO4 level every couple of weeks and when I see the levels climbing I'll know it's time for a GFO change. I was using a color chart PO4 tester but find the Hanna checker is the most accurate for phosphates and use Salifert kits for everything else.
This is what I did for my system and it seems to be working for me so far, hope this helps :smile:

use precision solutions phosphate solution to bring it down and gfo to keep it stable

Hi,

The Foz Down will work very well for your system. It is safe for all the inhabitants of your tank and a lot easier to use than GFO or Rowaphos. Once I started using Foz Down I threw the expensive High Capacity GFO and the PITA reactor to the curb. ;-)

Cheers,
Tim
