Lower nickel content (below 75 g/L) requires higher boric acid. The pH of the sulfamate nickel plating solution is important in controlling the deposit characteristics. A low pH, below pH 3.5 reduces the cathode efficiency, slows plating rate slightly, but does not change the deposit. Barrel plating must be done at a pH of 3.2 to 3.5 in order to

Rinse water criteria for electroplating
A. Hi Terry. I would make the assumption that 4 stages is more than sufficient to remove all of the nickel plating solution even if the water is cold. For "beautiful parts" I think you need to be concerned with the dissolved salts in the rinse water, such that running the last stage as a recirculating DI rinse rather than as city water would be an improvement.
