[Suzie Q]

A lot of people mention using Flourish and Flourish Excel(?) for plants. The bottle that I looked at lastnight (Seachem's Flourish) contains .0001% copper. Will this be ok for my shrimp? or should I get another type of fert (Petsmart did not have Excel). I have not found (locally) any ferts that don't contain copper. Is this small amount ok for shrimp?
Thanks.

Fluorish Comprehensive is fine with shrimp. Some of the hardcore shrimpkeepers will disagree with me and say it will kill shrimp, but this is not true.

It isn't enough to harm inverts. I think flourish has the lowest amount of copper out of the most commonly used trace ferts.

Thanks for the replies. I was so worried that it would hurt the shrimp, I forgot to search the forum first. I wanted to take this time to appoligize for this.

I wouldn't worry about it.....I have dosed 2x the normal amount of flourish then I switch to gregwatson's and dosed 2x the rec EI amount and never had a problem with my RCS,CRS,Tigers,Amanos,Sp.Blue

I think that depends on the size of your tank and the amount of plants in it and if it was CO2 injection or not.
A 5G tanks with a few plants and none CO2, with a 2X dose of Excell will definately do some damage to your shrimps. Especially your baby shrimps.
