Red Cherry Shrimp & Flourish

[Welsh]

I just added more RCS, which I haven't had for quite a while. I was just wondering, since they are sensitive to copper, can I still use Flourish comprehensive, or not? I know there is very little copper in this fertiliser, but I thought I'd ask just in case. Also, is Flourish Excel still safe to use?

Thanks

I've never used flourish, but if it has copper in it, it should not be used with invertebrates. It might not be enough to kill them, but it could stress them out. And this stress could do a lot of bad things. So I wouldn't recommend it. I don't know about the excel stuff, but copper is a no-no when it comes to anything invertebrates.
