I just switched to a new water conditioner and realized about an hour after changing the water that I'd seriously miscalculated the dose - instead of 1/2 mL that I should have used, I used 1/2 tsp, or 5 mL! As soon as I realized my mistake I did 100% water change using the proper concentration. The fish seems to be doing fine (he never really seemed not fine) - can I hurt him by using waaaayyyy too much water conditioner like that? If so, what should I be on the lookout for or what else should I do? If it matters, the water conditioner is API Stress Coat. Thanks!
