Seachem Excel should just contain polycycloglutaracetal, no copper. If you want a cheaper version, you can buy glutaraldehyde (usually Metricide 14 or 28) and dilute it.

As for plant safety, there's this thread here. Google will pull up more results as well.

Contains only 0.0001 percent. Some have good results using it with mosses and some do not. I do not have a problem using it with my mosses. Below is what it contains. I have amano shrimp in my tank that use this and they are good and healthy.

Those are the ingredients for Seachem Flourish, which is a micro fertilizer. Seachem Flourish Excel is a completely separate product used as a secondary carbon source, and contains no copper.

Bump: It should be fine with mosses in normal doses. I have seen it cause problems when applied directly to mosses through a syringe in high concentrations. But if you are just adding it to the tank according to the directions on the bottle, it will be fine.

My bad you are right. I looked at my wrong bottle. Excel does not contain any copper that is the flourish.
It is seachem flourish, not excell that I am talking about. Thank you all for the info.

I'm confused.
Think they meant Flourish originally even though asked about excel. A tiny bit of iron in Flourish but none in excel.
..or they were asking about excel while looking at the back of the flourish bottle? :)
I did mean flourish, not excell. Asking about copper amounts. Sorry for all the confusion I caused.
