Can you explain how you overdosed the tank? You added 2 tablespoons of diluted Kalk solution? Kalk paste? Kalk powder? How do you normally dose?I just overdosed my tank and don’t know what to do I accidentally dumped about 2 tablespoons into my 20 gallon aquarium I did a water change but don’t have enough for a full water change I am currently running my RO also my blenny I found laying on the substrate breathing heavily so I put him into a bucket of clean saltwater with a air stone. Till I can do a full water change what do I do and what can I do to help my blenny?
