I'm wondering if they'd have to list things like copper etc on this document if it contained anything other than LC?

I checked the MSDS and it does not list copper. It does not list the purity of the LC which can be from 99% to 99.999%. It also does not mention the liquid used to dissolve the LC in. So who knows what is exactly in the product.

The reason for using LC in pools is to control algae. They also use Copper sulfate to control algae in pools. It could make a more powerful product to control algae by adding copper to the LC. They could also try cutting costs by reducing the LC and adding Copper to keep the net effect the same. There is so many variables that could affect the ingredients it's hard to know. To me it's not worth the risk of experimenting by using a pool based product.

For a 100 gallon system a $30 bottle of Foz Down will neutralize 10mg/l of Phosphate. This would probably last for a year with an average fish load. I have personally tested the aquarium grade for 3 years on my acro culture system with no ill effects. I know the product is safe for acros, clams, shrimp etc. I have no experience with the pool product.

Is money saved by buying the pool product and is it worth the risk of not knowing until it's too late.

Cheers,
Tim
