Read they can kill Vals?
Yes, glutaraldehyde can kill Vallisneria
I use CO2 now but interested in these type products for a shrimp tank as rather not use C02 .
If you try it could you let us know how you like it?
Glutaraldehyde is just as dangerous to shrimp as CO2. I have killed 30+ shrimp at once with a slight overdose.
