Kz flatworm stop

Is anyone using this stuff? I bought a bottle 2 weeks ago because after reading up on it it basically is supposed to boost your coral health and increase slime coat and coloration. I don't have flatworms "knock on wood".
I have seen a nice improvement in all of my sps since using it polyp extension and coloration. However I also started noticing hair algae popping up.
I thought no big deal , but it seems to be getting worse.
I'm thinking it's the flatworm stop.
I put a drop of it with some ro/di in my Hanna phosphate meter and got a reading of 1.22
Any input? Maybe it's only for zeo systems?
Before anyone says it , I run a somewhat low nutrient system , frequent water changes , feed lightly, big skimmer , large macro fuge , lots of gfo , and good bulbs

 

I heard it was "snake oil" from a reputable source.

 

After lot's of googling that's kinda what I'm thinking.
There has been a noticeable improvement in my acro's although who know if it's from the flatworm stop.

 

True, it could be hundreds of things. Whether its directly related to the flatworm stop we cannot determine for sure

 

Yeah my guess is the Metal Halide's ;D

 

what made you decide to use flatworm stop if you dont.have flatworms. Or am i missing something.

 

Basically as a prophylactic measure.
