my tank has been running for about 6 months and i wanted to add some more sand b/c i got a red coris wrasse about a month ago. so i got another bag of seachem grey coast(what was originally in their) and ran water through it and mixed it to try and get all of the "dust" out of it. I added it by putting it in a zip lock bag first and cut a hole in it once it was in the tank. anyways the tank still got cloudy and i want to know if this is at all dangerous to the fish?
