I agree. Obviosly no one would want to consume the chemicals, right? I mean thats why they have a disclaimer, to avoid any incidents....
We have this 55 gallon aquarium and had 25 tetras that were all grey and white and dusky looking. Very poor health. Poured in a couple grams of rc's and it is amazing how these tetras brightened up overnight...Many looked like Neon tetras and others shined bright red and white just like Cardinal tetras. Made em grow much larger and they were far stronger and healthier also. Doubled their reproduction rate. A must for anyone thinking of owning an aquarium. Incredible..Lasted for months.
