What is the acceptable level of Phosphate in an SPS tank?

What do you guys use to measure an accurate phosphate reading? Thanks

HANNA meter ULR you can find on BRS.

I find the Hanna eggs to be somewhat inconsistent. But with the average of a few readings, you can get an accurate result..
My personal favorite is the Elos High Resolution phosphate test kit but it can be tricky to find in some areas.. has to be the righ Resolution, not the regular one.
Even the Red Sea one isn’t bad at lower levels..

This is a very strong statement. The expression "long run" is a like a piece of string. How long is a piece of string?

If we agree how long is.....a long run reef, please someone explain to me , why if corals thrive (fast growth rates +excellent coloration) under high po4 ( >0.1 or even a lot higher ) for let's say more than 6 months, why in the "long run" will have problems? If the high po4 levels affects them negatively, shouldn't we notice reduced growth rates or browning more or less sooner?



Edit: I should have quoted denadai post rather yours Bulent.
