No, not a good idea. Mixing chemicals is never a good idea, and right after stirring up everything in the tank, makes it a very bad time to do so. After a water change, you should use only Aquasafe out of the ones you mentioned. Easy Balance is supposed to be added once a week, and not after a water change. Florapride should be added once a month, and not after any other chemical as chemicals could remove the fertilizer or make it ineffective. Algae Control is a very strong chemical and should never be used with any other chemical at all. Dose once a month as a preventative, or once every three days for up to three doses, for an algae issue. Do NOT overdose.
