What PO4 level you have the best results on your SPS.

This is not about who has the best SPS, but more like that we all like to know that it can be different in a way with same results.

Ok, I go first.
As I used to run full ZEO and the PO4 was right at 0.02 or 0.04.
Now with AP it's between 0.08 and 0.12.
Result is corals are deeper in color, but awesome growth and PE.

Okay im gonna get into it all :)


We try to keep our Phos as low as possible, we keep it .01-.03 But for some reason when we keep it higher like .05-0.9 Stuff tends to Start overload with some growth. Maybe its just me and my imagination.

Alk we keep as always a stable 8-9. no higher then that no less.


salinity we keep at 1.024-1.027

Temp- is a stable 76-78. always, in less put higher or lower.

People also need to list what test kit their using to make this data useful IMO. For instance the Hanna Phosphate 713 checker has a 0.04 error factor. So if it reads 0.04 it could be 0.00 or 0.08 and if it reads 0.00 it could be a tank crash or you're fine at 0.04. I've also gotten bad batches of reagent and it's read 0.15 and it was really 0.02.

The most accurate tester is the Hanna 736 Phosphorus checker. That said my phosphate is 0.036.

Good point!

Although we just talking PO4 here I list all my test kits for reference.

Alk, Hanna
PO4, Hanna http://hannainst.com/usa/prods2.cfm?...01&ProdCode=HI 96713
Cal Pro, Red Sea
Mag Pro, Red Sea
K Pro, Red Sea and Korallen-zucht (zeo)

FYI, I send my water off every month to http://aquariumwatertesting.com/

So far so good but the day that they check I'll make some own test on ALK, CAL, MAG, K, and PO4.
Just to see if my testers are off and if so by how much!!

K is a easy fix but dose slow.
Silica and copper are different.
How is your livestock doing so far?
Corals looking good?

Sorry didn't want to hijack your thread, but I will say that I had the test ran before I made a few modifications to my system and it's headed in the right direction now. I just wanted to show the phosphate reading from my test results.

So I have pictures of what my Hanna 713 registered the day I took the water samples...which was an exact match of 0.02

And this was what the Hanna 736 reading was that day too..which reads 0.036

Now interestingly enough I used the reagents from my Salifert Phosphate test kit to run these tests that were confirmed. I will never use the Hanna reagents again. They're just too inconsistent for me from batch to batch.
