Ferts Safe For Shrimp?

[adrianborg]

Does anyone know if any of the following fertilisers are safe for cherry shrimp?

- Ferropol liquid
- JBL Ferropol 24
- TetraPlant Crypto tablets
- TetraPlan Plantamin liquid

The first two mention they contain copper. The Tetraplant doesn't mention what it contains.

Thanks for anyone who can help

I'd put money on them all being safe for shrimp. They won't contain enough copper to harm shrimp.
