Yes and no. (yes now, no later) Yes it would make the bioload increase (your levels worse) on the tank but that should have been day one when you started adding stability. Now your not using stability and once you establish a colony with such a small bioload then add larger fish, the baterial colony won't be able to keep up, not by a long shot. You'll be still doing WC's and going through another cycle, it may be mini and only last a few days or could be weeks waiting for the colony to multiply. IMO you should add more fish (bioload) and dose another round with stability since the majority of it went to waste. You basically want the bacterial colony to multiply to as close to the size, as can consume your planned stocking bioload. Does that make sense?
