Phosphate E + Testing Question

[happysalt]

Hi I was wondering if anyone has any experience with Phosphate E. On the instructions it says that:

"Particulate material not removed by filtration will remain inert and the bound phosphate non-reactive indefinitely under normal aquarium conditions."

Does this mean that it will still show up in a hanna checker phosphate testing kit and could lead to me overdosing thinking that phosphates are higher than they actually are?

Sounds like Lanthanum Chloride to me (I do not know of that specific brand). Lanthanum Chloride will bind Phosphate and it will remain bound in the tank. It will NOT show up on a Phosphate test kit. You essentially remove it from the water column.
