Water changes almost always cause a drop in ORP. It is no concern at all. It just means that the balance of ions like iron are in more reduced forms (Fe++ compared to Fe+++). How much it happens and how long it last just depends on how many electrochemically active ions were present. I would also not conclude it is better (or worse) for it to go down less and bounce back faster.

FWIW, if the alkalinity is the same, the salt mix will not have any lasting impact on the pH. It is the interplay of all of the sources and sinks of CO2, along with alkalinity, that determines the tank pH.
Thank you Randy. One last question. What are you feelings on Organic Salt mixes?
What would be a true test that i could do to see if I should change???
I am still in shock that my Ozone really only needed one hour to recover the ORP reading of 400. I got up this morning and it is now 450 and the unit is set for 400. The probe is clean no slime on it. It was going to about 425 on its own before i tried the new salt.

One day I will not have to scrape my windows!
