BY MISTAKE, instead of dosing my EI mix (which I pour into a shot glass of 50ml), I poured 50ml of Seachem Excel into my 30gal tank! I have been dosing daily with 10ml and the tank is looking very good in my humble opinion and humble expectations, but now I am worried having clearly severely overdosed Seachem. I have no inverts, just a few fish and quite a few low tech plants.
Should I do a large water change??
