Is this product safe for fish

Yes. I get a great return on my aquatic plants and doesn't hurt the fish. Been using it now for a few years. Fyi..... my Angels are breeding and giving off healthy broods.

Does this product have copper in it?

There is a very small amount. Small amounts like in this product are still safe from snails, shrimp, ect. If copper is at the bottom of the list it’s safe, you want to watch out for when Cooper it towards the top of the list

I am new at keeping live plants in fact I am waiting on my first order. I purchsaed this plant food but was also told I needed Flourish Excel, the ingredients are organic carbon. Are the these the same thing, ( plant food) ? and do I need to use both at the same time? Thank you!

I have found the following to be helpful. If you are comfortable with the API products you will also want to order API co2 booster. Every four months I also insert into the soil API plant food. I used these two products for the past year with my planted tanks. I currently have three planted tanks. All are flourishing and doing great.

Will this work with an under gravel filter system?

Yes , it works with undergravel filtration systems.
