Hello, I was wondering if seachem flourish tabs are safe to have in an aquarium that houses alpine newts? It says the product contains "essential trace elements, amino acids and vitamins. Rich in iron, manganese, magnesium, calcium, potassium, inositol, choline B12 and biotin". My aquarium is not dirted and I cannot be bothered to make it dirted. so I think this may be my only option. I do hear you can make diy root tabs so maybe I could make newt safe ones if these are not safe? Thank you for your time.
