You can’t overdose biospira, I usuall squeeze out the sponge and pour the bio on the sponge also I’ve never had trouble with copper killing the bacteria that convert ammonia but I have had the cu kill the bacteria that coverts nitrite. Ammonia will read good on the seachem badge but nitrite will shoot up. This is less of a problem in a tank due to the chloride blocking the absorption of the nitrite by the fish
