What is this stuff ??? A few drops and your phosphates go away ?
Sounds to good to be true...Anyone know anything about this product ?

This could be some chemical compound which creates insoluble
phosphates which then will be removed by the filters or collect
with detritus on your sump floor... They mention clouding...
So some precipitation of insoluble material occurs for sure.
I think it is similar to iron based phosban but in a liquid form.

You could ask the manufacturer what the active ingredient is
and then it would be more clear how the product works and
what you really add to the water column. This would be important to
avoid known problems caused with aluminium based phosphate removers.
