So I have had an issue in one tank recently where it is reading .25 ammonia and until recently I had been flipping out trying to fix it. Long story short it is a false positive due to ammonium that got introduced from regular non DI RO water use by mistake, I have since fixed the issue. Makes sense as well given this particular tank has acros and several sensitive species that should of been dead had it been ammonia. Anyways, I have read ammonium except in very high concentrations is non toxic, but will my biological filtration remove it the same as ammonia so I can be rid of the false positive? If not is there a filtration resin I can use to avoid disrupting the balance already established?
