Can anyone help me get my phosphates down. I’ve been struggling with this for 2 years.?tried vodka, GFO in a reactor and Awesome Aquatics Pho’s-Extracts in a reactor. My phosphates are still running .58 ppm. Anyone have any other suggestions?
 
Heres a good link with a study going on right now with members here seems they are having success.

 
@Deborah Armay I can't help with your phosphate problem. I'm having a similar problem but I'm just 4 months in to the hobby. My phosphates are high (0.9) my alkalinity is at 15.1!!!! I've done water changes every week for the past 3 weeks but nothing changes. I decided to test the water coming out of my RO/Di and it was even worse. Is it possible that my RO/Di filter isn't working??? All of the filters in it are like a month old.... I don't want to mix salt in it and waste my salt with water that is already bad. I even took a sample of my display water to me local store to have them test it and they could even advise me of what to do. (fyi I've never participated in a form chat so I don't know the proper etiquette or if its even ok to piggy back off your post. Please forgive me) Can someone please help
 
What is your guys feeding regime ?

A lot of times especially with new tanks it is simply an imlort export issue.

The link I posted is what you need to read through to help understand phos better.

@Debrah Armay in an older tank your phos could be in your rocks and to lower your water phos you need to get the bound phos out of your rocks now that they have stopped obsorbing it.

The linked thread explains it much better.

I was feeding my 2 small clown fish once a day but I have stopped as of this week and I'm going to 2-3 times a week. I also just added Cheato to my sump last week. Hope to get the phosphates down. But my ALK is off the charts too!
 
I’m feeding every other day reef roids, rod’s frozen. Spot feeding corals
 
Reef roids will send your phosphates up...i would go very light on roids. I switched to benepets and now i'm trying coral feast
 
Thanks. I read the article but I’m a little confused. Are they recommending taking out all ur rocks and cleaning or using Lanthanium chloride?

That what I got out of it too and was wondering the same thing! I guess like one at a time but spaced how many days apart after putting them back in?

It all depends on how bad and old your rock is.

In New tanks it most likely is the rock that has stopped obsorbing phos and its actually the phos in the water column introduced by over feeding.

Slow down on food and clean the rocks first to see if that helps before stating the lanthanium.

It's using LC. The original post is asking if him 'removing and soaking the rocks in vinegar' have unbound the phosphate in it. He removed the rocks to remove the pest not phosphate. Then the thread eventually turned into the journey of lowering phosphate by using LC.
 
From my personal experience I had high phos tested with phosphorus checker for more correct. Bigger issue with hair algae as well. I went with GFO reactor that manage a little bit but months later I added LC and was dosing that to bring it down. My issue was the rock that was leaching out phosphate since I would stop feeding and dosing and still had high numbers. The LC and adding a power head filter to polish the water( similar to the Dutch system) did the trick to be honest and ever since then my tank has been .004 if not lower. I don’t use a reactor anymore and recently lessen with the use of power head since my numbers are so low. Was force to dose nitrates and phosphate now to keep corals happy. Only thing I would have done differently was not dose the LC daily to once a week and watch my numbers. It even force my to stop doing weekly water changes
 
Thanks for all the great info. I ordered the LC and getting up enough nerve to do it. Thanks to all!
 
Update. Started using LC at even lower dose than recommended and in 5 days my phosphates went from .5 ppm to 0. First time ever!!! Ca dropped some so I’m replacing that.
 
Stop feeding reef roids. The stuff is like liquid phosphate.


You need more export - this is a long term problem. Better flow/bigger skimmer/algae scrubber/etc.
So this is why my phosphate shot up. It's always been in the .05 to .1 range until recently. I make my own food and have started adding some reef roids to it, I'll stop with next batch I make.
