Phosphates are 1.67 - advice needed

[chicago]

BryanM.. like you I did the same and more.. I used it a few times and it just took one time and BOOM.... lost a personifer, regals and more. Just my take on this stuff. Need to watch the filiter sock.. if that gets clogged up and overflows.. well you get the picture... Yes works great.. but be very very careful if one goes down this road.

I'll just reiterate from other threads that not everyone is convinced the issues from lanthanum dosing relate to particulates caught by socks.

A competing theory relates to soluble lanthanum getting to fish gills.

I don't know which it is.

Hi all,

Current numbers:

Sal - 1.028
ph-8.11
temp - 78.3
alk - 9.95
ca - 373
N - 4.6
P - 1.67

All testing was done with Hanna and run 3 times each, these are the averages.

working to get the salinity down tonight.

My tank is 145 gals TSV and is 4 years old. Tank is currently LPS dominant and has always done great with LPS. My goal is to have an SPS dominant tank and SPS have always struggled in my system. For 3.5 years my nitrates and phosphates were stuck at 0. I have started feeding more heavily over last 6 months and things got dirty, now my nitrates seem to be in a better place but phosphates are way too high.


What is the best course of action to lower phosphates from this level to .02 -.1 range? Is it GFO? (I have a reactor and can set that up easily) or is it some other treatment?

The fish are all tangs and a Goby so just want to know what the safest and most productive course of action would be here.

Thanks for any help

GFO, but go slow with it. I mean, start with half of what the directions are.
